“…In several works, in which the authors paid considerable attention to the mechanisms of these processes, it was possible to synthesize cerium oxides with the unusual structure, morphology, and texture, and with very impressive catalytic properties. For example, a few works [ 37 , 42 , 75 , 94 ] describe the synthesis of hollow ceria particles and structures with mesoporous walls, exhibiting not only high catalytic activity, but also amazing stability in flow systems. In addition, a detailed study of the mechanisms makes it possible to reveal the role of auxiliary substances—ash impurities, complexing agents, solvents, precipitants, swelling agents, and with their help to further increase the catalytic efficiency of the final oxide systems.…”

“…The biotemplate nature strongly influences the structure and porosity of the synthesized oxide. A variety of biomaterials, such as lignocellulosic biomass and products of its processing [ 58 , 59 , 60 ], wood-based materials [ 48 , 49 , 50 , 57 , 89 ], plants’ leaves and flowers [ 52 , 53 , 58 ], cotton [ 90 , 91 ], eggshells [ 55 ], materials of animal origin [ 92 , 93 ], microorganisms [ 54 , 94 , 95 ] and so on can be used as biotemplates.…”

“…Small CeO 2 mesoporous hollow microspheres (1.5–2 μm in diameter, S BET = 39 m 2 /g) were prepared using the yeast template [ 94 ]. The authors suggested that the yeast acted as a solid frame for the deposition of cerium hydroxide.…”

Porous oxide materials are widely used in environmental catalysis owing to their outstanding properties such as high specific surface area, enhanced mass transport and diffusion, and accessibility of active sites. Oxides of metals with variable oxidation state such as ceria and double oxides based on ceria also provide high oxygen storage capacity which is important in a huge number of oxidation processes. The outstanding progress in the development of hierarchically organized porous oxide catalysts relates to the use of template synthetic methods. Single and mixed oxides with enhanced porous structure can serve both as supports for the catalysts of different nature and active components for catalytic oxidation of volatile organic compounds, soot particles and other environmentally dangerous components of exhaust gases, in hydrocarbons reforming, water gas shift reaction and photocatalytic transformations. This review highlights the recent progress in synthetic strategies using different types of templates (artificial and biological, hard and soft), including combined ones, in the preparation of single and mixed oxide catalysts based on ceria, and provides examples of their application in the main areas of environmental catalysis.

This review covers recent progress and advancements in bio‐templating nanomaterials for use in energy applications. Viruses, bacteria, and fungus, as well as plant and animal biomasses such as woods, coffee grounds, and crab shells, can be used as the templates or carbon sources for metal‐ and carbon‐based nanomaterials. Here we provide an overview of each of these materials as a template, with emphasis on the synthesis methods and qualities of nanomaterials fabricated using these templates. Research in this field is understandably diverse, as such, we aim to further its development by providing a timely summary of current research. We anticipate that this field will continue to prove highly applicable to the salient and growing topics of renewable energy.
