MOF-derived hexagonal In₂O₃ microrods decorated with g-C₃N₄ ultrathin nanosheets for efficient photocatalytic hydrogen production

Abstract

This study reported the establishment of a highly-efficient In2O3@g-C3N4 heterostructure with intimate contact for photocatalyzed H2 evolution by incorporating the g-C3N4 ultrathin nanosheets on the surface of MOFs-derived hexagonal In2O3...

A one-step solvothermal synthesis of the topological insulator Bi2Te3 nanorod-modified TiO2 photocatalyst for enhanced H2-evolution activity

“…Both the Bi 2 Te 3 /TiO 2 (0.5 wt%) and Bi 2 Te 3 /TiO 2 (5.0 wt%) materials display a lower overpotential in the dark in comparison with TiO 2 , suggesting that Te atoms on the high conducting states of Bi 2 Te 3 can act as highly efficient active centers to markedly facilitate the interfacial hydrogen-production reaction of TiO 2 . 55,56 Moreover, the carrier migration of various samples can be further determined by the i – t and EIS curves (Fig. 10D and E).…”

“…10B exhibits the TRPL spectra of the TiO 2 photocatalyst before and after modification (t ave = 11.16 ns) and Bi 2 Te 3 / TiO 2 (0.5 wt%) (t ave = 10.07 ns) photo-catalysts present a higher average fluorescence lifetime compared to naked TiO 2 (t ave = 9.41 ns), proving that the effective interfacial electron transfer from TiO 2 to Bi 2 Te 3 . 21,54 Herein, the extended fluorescent lifetime can boost more photogenerated electrons to participate in 55,56 Moreover, the carrier migration of various samples can be further determined by the i-t and EIS curves (Fig. 10D and E).…”

Novel CuBr-assisted graphdiyne synthesis strategy and application for efficient photocatalytic hydrogen evolution

“…1–4 Solar and hydrogen energy, among the numerous sources of clean energy, have piqued the interest of many academics due to their respective popularity and high calorific value characteristic. 5–10 Since the concept of photocatalytic hydrogen production was proposed a few decades ago, researchers have developed a variety of photocatalysts to pursue the use of abundant solar resources to achieve the efficient conversion of solar energy to hydrogen energy. 11–15…”

Rhus Semialata Derived Carbon Quantum Dots Decorated Pt Deposited TiO2 for Efficient Light‐Driven Hydrogen Production

“…One of the greatest and most practical solutions to the energy crisis and loss of natural resources is the production of hydrogen from water using photocatalysis and solar energy. As a part of this, researchers have progressed in examining several photocatalysts such as semiconductors, [7–8] noble metals loaded ‐semiconductors, [9–10] spinel oxides, [11] Mxenes, [12–15] and MOF‐derived In 2 O 3 , etc [16–17] . Numerous semiconductor‐based photocatalysts have been investigated for this purpose since the original study 40 years ago; TiO 2 is the most attractive substance that has been widely considered due to its low cost, high compound stability, and non‐toxicity [18–21] .…”
