Light-harvesting macroporous channels have been successfully incorporated into a mesoporous TiO(2) framework to increase its photocatalytic activity. This bimodal porous material was characterized by X-ray diffractometry in both low-angle and wide-angle ranges, N(2) adsorption-desorption analysis, scanning transmission electron microscopy, FT-IR, diffuse reflectance spectroscopy. Ethylene photodegradation gas-phase medium employed as probe reaction evaluate the reactivity of catalysts. The...

Au-Plasmon-induced resonance energy transfer modulates the charge carrier energetics of ZnO nanosheets to trigger stoichiometric conversion methane into ethane and hydrogen.
Construction of internal electric fields (IEFs) is crucial to realize efficient charge separation for charge-induced redox reactions, such as water splitting and CO2 reduction. However, a quantitative understanding the transfer dynamics modulated by IEFs remains elusive. Here, electron microscopy study unveils that non-equilibrium photo-excited electrons are collectively steered two contiguous within binary (001)/(200) facet junctions BiOBr platelets, they exhibit characteristic Gaussian...

2D carbon nitride nanosheets have attracted ever-increasing interest in photocatalysis due to their unique structural advantages. However, the synthesized by traditional methods, such as post oxidation and liquid exfoliation, suffered from in-plane disorder with abundant defects, which seriously counteracts benefits for photocatalysis. Herein, it is demonstrated that polymer highly ordered structure (PCNNs-IHO) can be successfully prepared on-surface polymerization of melamine on NaCl...

Poly (triazine imide) (PTI/Li+ Cl- ), one of the crystalline versions polymeric carbon nitrides, holds great promise for photocatalytic overall water splitting. In principle, activity PTI/Li+ is closely related to morphology, which could be reasonably tailored by modulation polycondensation process.

In situ photo-deposition of both Pt and CoOx cocatalysts on the facets poly (triazine imide) (PTI) crystals has been developed for photocatalytic overall water splitting. However, undesired backward reaction (i.e., formation) noble surface is a spontaneously down-hill process, which restricts their efficiency to run splitting reaction. Herein, we demonstrate that could be largely promoted by decoration Rh/Cr2 O3 as H2 O2 evolution cocatalysts, respectively. Results reveal dual greatly...
