Design and synthesis of multistructured three-dimensionally ordered macroporous composite bismuth oxide/zirconia: Photocatalytic degradation and hydrogen production

Recent Progress of Three‐dimensionally Ordered Macroporous (3DOM) Materials in Photocatalytic Applications: A Review

“…3DOM materials with unique framework shapes obtained by various stacked microsphere crystal arrangement structures have different properties. For example, Zhang et al [89] prepared 3DOM Bi 2 O 3 /ZrO 2 composite photocatalysts with tetragonal "fishing net" and hexagonal "honeycomb" structures by sol-gel method using PS as microspheres templates with bcc and fcc stacking arrangement, respectively (Figure 8a-f). Compared with the hexagonal "honeycomb" structure, the tetragonal "fishing net" structure possessed a larger empty space to allow the exchange of reactant molecules within the catalyst and more skeletal parts to provide more active sites.…”

Synthesis and Characterization of Boronate Affinity Three-Dimensionally Ordered Macroporous Materials

“…Consequently, 3DOM materials are widely utilized in catalysis, separation, the environment, sensors, and batteries [ 27 , 28 , 29 , 30 , 31 ]. However, until now, most 3DOM materials have been prepared in the form of thin films or block monomers [ 31 , 32 , 33 , 34 ], and there has been little research on the preparation of spherical 3DOM materials, which has limited the development of these materials in the field of high-efficiency separation and adsorption.…”

An efficient and recyclable Ni2P–Co2P/ZrO2/C nanofiber photocatalyst for the conversion of plastic waste into H2 and valuable chemicals

“…22 When ZrO 2 is rendered with nanometer size and a unique morphology with a channel structure, it exhibits a large specific surface area, excellent adsorption capabilities, and a heightened capacity for strong ion exchange. 23 Moreover, besides demonstrating commendable catalytic performance, ZrO 2 serves as a versatile catalyst support capable of accommodating various catalytically active components. 24 ZrO 2 is a transition metal oxide with a wide bandgap (ranging from 3.3 eV to 5.1 eV) and exhibits significant photocatalytic activity under ultraviolet light (approximately 5% of the solar spectrum).…”
