“…Also, due to the hierarchical structure of the composites, TiO 2 @graphitic carbon showed higher activity in Cr 6+ reduction under visible light (almost complete degradation after a 240 min period) [150]. Magnabosco et al [151] produced some TiO 2 /SiO 2 catalysts that proved to be efficient in the degradation of rhodamine B with simulated solar light. The catalysts were designed using sea urchin spines.…”

“…To introduce more porosity to the structure, polystyrene nanoparticles were deposited on the surface of the spine, and some TiO 2 and SiO 2 precursors were added to form the structure. [151]. Other TiO 2 nanoparticles with dominantly exposed {001} facets from cellulose nanocrystals with high catalytic performance in degrading rhodamine B were also developed [152].…”

In the last few years, researchers have focused their attention on the synthesis of new catalyst structures based on or inspired by nature. Biotemplating involves the transfer of biological structures to inorganic materials through artificial mineralization processes. This approach offers the main advantage of allowing morphological control of the product, as a template with the desired morphology can be pre-determined, as long as it is found in nature. This way, natural evolution through millions of years can provide us with new synthetic pathways to develop some novel functional materials with advantageous properties, such as sophistication, miniaturization, hybridization, hierarchical organization, resistance, and adaptability to the required need. The field of application of these materials is very wide, covering nanomedicine, energy capture and storage, sensors, biocompatible materials, adsorbents, and catalysis. In the latter case, bio-inspired materials can be applied as catalysts requiring different types of active sites (i.e., redox, acidic, basic sites, or a combination of them) to a wide range of processes, including conventional thermal catalysis, photocatalysis, or electrocatalysis, among others. This review aims to cover current experimental studies in the field of biotemplating materials synthesis and their characterization, focusing on their application in heterogeneous catalysis.

“…Inorganic [1,2], organic [3][4][5], polymeric [6], and hybrid inorganic-organic [7][8][9][10] porous materials play a key role in many technologies including water treatment, gas capture and separation, supercapacitors, catalysis, sensors, tissue engineering, drug delivery, and photonics [11,12]. The pore walls of porous materials can interact with atoms, ions, and molecules, or load and hold solid particles, liquids, and gases [13][14][15].…”
