terol in a vegetable oil or fat is a clear
indication that animal fats have been
added. Michael H. Gordon discusses the
analysis of these constituents in Chapter
6 (pp. 143 – 155). Chemometry using
statistical methods also has applications
to problems of authentication, as
explained by R. Aparizio and R. Aparizio-Ruiz in Chapter 7 (pp. 156 – 180).
I can thoroughly recommend this
book, not only for specialists concerned
with the authentication of food products, with quality control, or with food
research in academic or other institutions, but also for organic and analytical
chemists working on natural products.

The ubiquitous presence of porous
materials in our daily life is clear evidence of the importance of this class of
materials. From the charcoal that made
many of the drawings in prehistoric
caves, to the famous Portland cement,
and to many of the catalyst supports
used in the modern petroleum industry,
all these solids share a common characteristic: structural porosity. The sizes of
the pores range over several orders of
magnitude, from micrometers or larger
to nanometers and smaller.
In the past several decades, research
on porous solids has been vastly
expanded. The researchers in the field
now include chemists, chemical engineers, materials scientists, and physicists.
Although there are increasing numbers
of journals, books, and monographs, as
well as international conferences, dedicated to this particular research area,
the authors note in the foreword of this
handbook that “no attempt has been
made to produce a comprehensive
account of the properties and applications of the different classes of porous
This five-volume, 3000-page handbook is the first such attempt, and is
probably the most comprehensive
survey of the vast array of different
porous materials that exists. It covers
almost every important aspect of porous
solids, from the synthesis of various
porous materials to their characterization, from their mechanical behavior to
many of their important industrial applications. The handbook is very well
organized and coordinated. It starts
with a concise and general introduction
to porous materials. It is here that the
authors introduce the definitions, terminology, and classification of the different
pore structures. Considering the diverse
backgrounds of the researchers in the
field, this introduction is important and
will help greatly in unifying the language
from different disciplines as well as
laying a solid foundation for the survey
and discussion in the rest of the chapters.
Immediately after the introduction,
the handbook continues with a detailed
survey of the different techniques used
for the characterization of structures
and properties. All these techniques
are carefully reviewed in detail in separate chapters, covering fractal analysis,
microscopy and stereology, scattering
and diffraction methods, gas/liquid
adsorption, mercury porosimetry, thermoporometry, surface acidity analysis,
NMR techniques, and positron annihilation spectroscopy. These state-of-theart techniques have been used to probe
different aspects of porous solids, such
as local structural ordering, coordination environment, and porosity. With
lots of illustrations and references, these
chapters are easy to follow. For
researchers who want to learn about
new characterization techniques this is a
good starting point.
Volumes 2 and 3 of the handbook
provide a thorough coverage of almost
all possible porous solids. The treatment
starts with a discussion of some general
principles for the synthesis and modification of various porous materials. This

is followed by a long list of porous
materials distributed in 11 chapters. In
each chapter the synthetic methodologies and the unique structural characteristics of individual types of porous solids
are thoroughly reviewed. The list starts
with the clathrate and inclusion compounds, followed by crystalline microporous solids, porous metal-organic
frameworks, pillared layered structures,
mesoporous oxides, anodic alumina,
porous glasses, various porous transition
metal oxides, porous carbon, polymers/
resins, and aerogels. Not surprisingly,
the authors have put significant emphasis on the crystalline microporous solids,
some of the most important materials in
this area, devoting about 500 pages to
this class of porous solids. They provide
extensive coverage of different zeolite
framework types, processes for synthesizing them, their structural characterization, and their applications in ion
exchange, catalysis, and separation.
Another important feature of this list is
a comprehensive survey of porous transition metal oxides and porous carbon
(which includes activated carbons, coke,
and carbon nanotubes). Compared with
that, mesoporous materials are covered
relatively briefly with only one chapter
on their synthesis and mesostructures.
Volume 4 deals with a very important phenomenon associated uniquely
with porous media: that of mass transfer. Theories of diffusion and adsorption
within porous media are surveyed and
their implications for chemical transport
and reaction are discussed.
The handbook ends with a significant portion of the chapters devoted to
the technical applications of porous
solids. This part of the survey is clearly
an essential aspect of porous solids since
many of them are already extensively
used in industry. The authors review
several important applications in gas
adsorption/separation, porous membrane processing techniques, gas/liquid
chromatography, groundwater treatment, catalysis, and biomedical applications. Emerging applications in optical
and electronic areas are also briefly
covered in the final chapter.
The editors of this comprehensive
Handbook of Porous Solids have set
themselves the ambitious task of organizing and surveying many decades< work
on porous media. To successfully coorAngew. Chem. Int. Ed. 2003, 42, 1683 – 1685
dinate and assemble the contributions
from about 120 authors on such a wide
range of topics is certainly a remarkable
achievement. The contents are arranged
in a very coherent and systematic fashion, with a significant amount of up-todate literature references and many
informative illustrations, although the
authors could have avoided repeating
the same illustrations on several occasions. A very extensive subject index is
provided at the end of Volume 5. This
serves as a reliable resource to help
researchers locate information on specific topics. One should also note that
many of the chapters can stand alone
Angew. Chem. Int. Ed. 2003, 42, 1683 – 1685
and be read independently. The readers
will soon discover that almost anything
related to porous media can be found
within this handbook, whether it is
different types of materials, characterization techniques, or technical applications. There is only one topic to which
the editors could have usefully devoted
more pages: the emerging area of macroporous solids. These are the most
recent addition to the family of porous
solids, and they are poised to have a
significant impact in catalysis and photonics.
Overall, this handbook reflects the
collective efforts by the editors and
authors. The achievement is really
remarkable and deserves praise. I
believe that the Handbook of Porous
Solids is a must-read for researchers
already in the field, as well as those who
want to enter this fascinating area. It will
surely become the standard reference
work for researchers coming from many
different disciplines. It will serve as the
cornerstone to promote the establishment of common ground for future work
on a diverse range of porous materials.
