Abstract

methods can be further classified to the soft templating method and hard templating method. [57] It has been discovered that some soft matters, such as supramolecular, surfactant micelles, and polymer vesicles can be applied to induce the formation Yanze Wei received his B.S. and M.S. degrees in chemistry from Shandong University, China (2012 and 2015). He then obtained his Ph.D. degree from University of Science Technology Beijing in 2019. He is also a joint Ph.D. student in Institute of Process Engineering, Chinese Academy of Sciences under the supervision of Prof. Dan Wang. His research interests mainly focus on discovering the structure-performance correlation of hollow multishell structured photocatalysts, and mixed-dimensional inorganic/organic heterojunctions. Shouhua Feng an academician of the Chinese Academy of Sciences (2005), obtained his Ph.D. degree in chemistry at Jilin University, P.R. China (1986). He has been engaged in inorganic solidstate chemistry and preparative chemistry for more than 30 years. He has found the triple valence states and atomic scale p-n junctions in perovskite manganese oxides. In recent years, he focuses on the research of functional composite solids and chemical-medicine interdisciplinary.

In situ Irradiated XPS Investigation on S‐Scheme TiO2@ZnIn2S4 Photocatalyst for Efficient Photocatalytic CO2 Reduction

“…Apart from the charge carrier separation, the morphology of photocatalysts is another important factor to influence the photocatalytic performance. [15,17,19,37,38] Photocatalysts with hollow structures have attracted great attention owing to manifold advantages including larger specific surface area, abundant active sites, shortened diffusion distance as well as improved light reflection and scattering. [37,[39][40][41][42][43][44] Therefore, the design of hollow S-scheme heterojunction photocatalyst is of vital importance to enhance photocatalytic performance.ZnIn 2 S 4 , as a typical reduction photocatalyst, stands out for its layered structure, narrow bandgap, suitable redox potentials, and good chemical stability.…”

Hollow Multishelled Structured SrTiO3 with La/Rh Co‐Doping for Enhanced Photocatalytic Water Splitting under Visible Light

“…[6] First, increasing coverage of the solar spectrum by extending the absorption edge of the photocatalysts, especially utilizing visible light (400-700 nm) which occupies 39% of the energy of the total solar irradiation spectrum. [7][8][9][10] Second, sufficient La-and Rh-co-doped SrTiO 3 (STO:La/Rh) hollow multishelled structures (HoMSs) are fabricated by adding La 3+ and Rh 3+ ions during the hydrothermal process of converting TiO 2 HoMSs to STO HoMSs. STO:La/Rh HoMSs have successfully expanded the light absorption edge to 520 nm.…”

Encapsulation of Porphyrin‐Fe/Cu Complexes into Coordination Space for Enhanced Selective Oxidative Dehydrogenation of Aromatic Hydrazides

“…Constructing multifunctional hollow nanostructured materials from multiple components is considered to be one of the promising strategies to implement high-level applications requiring complex architecture with excellent catalytic performance. [9] As previously reported, a wide range of materials could be used as "host," such as holey Fe&N codoped graphene, [10] hollow mesoporous prussian blue nanoparticles, [11] carbon-based nanocages, [12] and layered double hydroxide nanocages. [13] To be more specific, layered void on the cage walls can support each other for enhanced mechanical stability, thus regulating the mass transport and enhancing the contact between the active catalytic components and reactant, which could significantly improve the catalytic performances.…”
