Polymer Modification Strategy to Modulate Reaction Microenvironment for Enhanced CO2 Electroreduction to Ethylene.
Modulation of the microenvironment on the electrode surface is one of the effective means to improve the efficiency of electrocatalytic carbon dioxide reduction (eCO₂RR). To achieve high conversion rates, the phase boundary at the electrode surface should be finely controlled to overcome the limitation of CO₂ solubility in the aqueous electrolyte. Herein, we developed a simple and efficient method to structure electrocatalyst with a superhydrophobic surface microenvironment by one-step co-electrodeposition of Cu and polytetrafluoroethylene (PTFE) on carbon paper. The superhydrophobic Cu-based electrode displayed a high ethylene (C₂H₄) selectivity with a Faraday efficiency (FE) of 67.3% at -1.25 V vs. reversible hydrogen electrode (RHE) in an H-type cell, which is 2.5 times higher than a regular Cu electrode without PTFE. By using PTFE as a surface modifier, the activity of eCO₂RR is enhanced and water (proton) adsorption is inhibited. This strategy has the potential to be applied to other gas-conversion electrocatalysts.Ting Deng, Shuaiqiang Jia, Chunjun Chen, Jiapeng Jiao, Xiao Chen, Cheng Xue, Wei Xia, Xueqing Xing, Qinggong Zhu, Haihong Wu, Mingyuan He, Buxing Han

Laser-induced immobilization of an amorphous iron-phosphate/FeO composite on nickel foam for efficient water oxidation.
A laser-induced immobilization strategy is applied to prepare an amorphous iron-phosphate/FeO (L-FePO) composite on a nickel foam (NF) support. By laser-irradiating an iron hydrogen phosphate (FeHP) precursor, a melting and oxidation process leads to the generation of L-FePO with hierarchical pores and an amorphous structure. L-FePO shows exceptional electrocatalytic performance for the OER in an alkaline electrolyte, demonstrating an overpotential of 256 mV at 100 mA cm, a Tafel slope of 71 mV dec, and good stability over 100 h. The active FeO, partially dissolved phosphate, and newly formed FeOOH species provide abundant active sites, contributing to the excellent OER performance.Yan Zou, Man Jin, Dongdong Zhu, Yu-Jia Tang

A ZnInS@ReS/AgInS-based photoelectrochemical aptasensor for the ultrasensitive detection of kanamycin.
An ultrasensitive photoelectrochemical (PEC) aptasensor was originally designed by using ZnInS/ReS as a photoactive material and AgInS as a signal amplifier. The signal amplifier AgInS was incubated on the terminal of H-DNA (immobilized on the ZnInS/ReS/FTO surface), leading to an enhanced photocurrent response. Then, due to the introduction of DNA2, the formation of a double-stranded structure caused AgInS to keep away from the electrode surface, and the photocurrent was reduced. In the presence of kanamycin, DNA2 was released from the system due to the competition relationship, and a restored photocurrent response was obtained. The combination of ZnInS/ReS and AgInS accelerated the electron transfer and enhanced the separation efficiency of photogenerated electron-hole pairs, resulting in an improved performance of the PEC aptasensor, which was capable of accurate and sensitive detection of kanamycin in actual samples.Xing-Pei Liu, Yuan-Yuan Tang, Jing-Shuai Chen, Chang-Jie Mao, Bao-Kang Jin
