| 1 | Photodeposition of CoOx and MoS2 on CdS as dual cocatalysts for photocatalytic H2 production显示文摘Photocatalytic Hproduction from water splitting has a promising prospect for alleviating energy and environmental issues.However,the fast recombination of photogenerated charge carriers limits the photocatalytic efficiency and its practical application.Cocatalyst engineering is an effective strategy to spatially separate photogenerated charge carriers.In this work,noble-metal-free MoSand CoOcocatalysts are loaded on CdS nanorods by a two-step photodeposition method.The MoSfunctions as the reduction cocatalyst to trap electrons and Co Oas the oxidation cocatalyst to trap holes.Transmission electron microscopy(TEM),inductively coupled plasma(ICP),X-ray photoelectron spectroscopy(XPS)and MottSchottky results demonstrate the effectiveness of photodeposition for loading MoSand CoOdual cocatalysts on CdS and their impact on the photochemical properties.The optimized CdS-MoS-CoOcomposite exhibits a high photocatalytic H-production rate of 7.4 mmol g^(-1)h^(-1)and an apparent quantum efficiency(QE)of 7.6%at 420 nm.Further analysis on time-resolved photoluminescence(TRPL)indicates that the introduction of dual cocatalysts greatly prolongs the lifetime of photogenerated charge carriers and deceases the charge recombination rates,consequently leading to superior photocatalytic H-production performance.This work provides a facile and effective strategy for the construction of highly efficient dual-cocatalyst-modified CdS photocatalyst for high-performance photocatalytic Hproduction. | Tingmin Di Quanrong Deng Geming Wang Shenggao Wang Linxi Wang Yuhua Ma | 2022 | Journal of Materials Science & Technology2022，，29： | 5 |

| 4 | Fluorescent lamp promoted formaldehyde removal over CeO_(2) catalysts at ambient temperature显示文摘Exploring an alternative strategy with high efficiency and low cost to abate formaldehyde(HCHO)in indoor environment,is of increasing significance for people’s health.CeO_(2) catalysts prepared by hydrothermal,precipitation and calcination methods were investigated for HCHO removal at ambient temperature.It is found that indoor fluorescent light visibly boosts the catalytic performance of CeO_(2) catalysts for HCHO decomposition at ambient temperature.Among the CeO_(2) catalysts,CeO_(2) prepared from hydrothermal method(CeO_(2)-H)exhibits a superior catalytic performance and an excellent durability by eight recycle times.Based on the characterization and analysis,the excellent catalytic performance of CeO_(2)-H is mainly contributed by its abundance of surface oxygen vacancies,and photogenerated electrons and hole activated by fluorescent light.This work shows a potential practicability in HCHO pollution elimination by taking full advantage of the existing lighting in indoor environments. | Zhaoxiong Yan Gang Huang Geming Wang Ming Xiang Xiaofang Han Zhihua Xu | 2022 | Journal of Rare Earths2022，40，6： | 1 |
