2Oxygen Reduction Reaction Catalyzed by Carbon-Supported Platinum Few-Atom Clusters:Significant Enhancement by Doping of Atomic Cobalt显示文摘Oxygen reduction reaction(ORR)plays an important role in dictating the performance of various electrochemical energy technologies.As platinum nanoparticles have served as the catalysts of choice towards ORR,minimizing the cost of the catalysts by diminishing the platinum nanoparticle size has become a critical route to advancing the technological development.Herein,first-principle calculations show that carbon-supported Pt9 clusters represent the threshold domain size,and the ORR activity can be significantly improved by doping of adjacent cobalt atoms.This is confirmed experimentally,where platinum and cobalt are dispersed in nitrogen-doped carbon nanowires in varied forms,single atoms,few-atom clusters,and nanoparticles,depending on the initial feeds.The sample consisting primarily of Pt_(2~7)clusters doped with atomic Co species exhibits the best mass activity among the series,with a current density of 4:16Amg^(-1)_(Pt)at+0.85V vs.RHE that is almost 50 times higher than that of commercial Pt/C.Bingzhang Lu Qiming Liu Forrest Nichols Rene Mercado David Morris Ning Li Peng Zhang Peng Gao Yuan Ping Shaowei Chen 2020Research2020,,1:1
3Ultrafast Preparation of Nonequilibrium FeNi Spinels by Magnetic Induction Heating for Unprecedented Oxygen Evolution Electrocatalysis显示文摘Carbon-supported nanocomposites are attracting particular attention as high-performance,low-cost electrocatalysts for electrochemical water splitting.These are mostly prepared by pyrolysis and hydrothermal procedures that are time-consuming(from hours to days)and typically difficult to produce a nonequilibrium phase.Herein,for the first time ever,we exploit magnetic induction heating-quenching for ultrafast production of carbon-FeNi spinel oxide nanocomposites(within seconds),which exhibit an unprecedentedly high performance towards oxygen evolution reaction(OER),with an ultralow overpotential of only+260 mV to reach the high current density of 100 mA cm^(-2).Experimental and theoretical studies show that the rapid heating and quenching process(ca.10^(3)K s^(-1))impedes the Ni and Fe phase segregation and produces a Cl-rich surface,both contributing to the remarkable catalytic activity.Results from this study highlight the unique advantage of ultrafast heating/quenching in the structural engineering of functional nanocomposites to achieve high electrocatalytic performance towards important electrochemical reactions.Bingzhang Lu Qiming Liu Chunyang Wang Zaheer Masood David J.Morris Forrest Nichols Rene Mercado Peng Zhang Qingfeng Ge Huolin L.Xin Shaowei Chen 2022Research2022,,4:0
4Rapid preparation of carbon-supported ruthenium nanoparticles by magnetic induction heating for efficient hydrogen evolution reaction in both acidic and alkalinemedia显示文摘Ruthenium has been hailed as a competitive alternative for platinum toward hydrogen evolution reaction(HER),a critical process in electrochemical water splitting.In this study,we successfully prepare metallic Ru nanoparticles supported on carbon paper by utilizing a novel magnetic induction heating(MIH)method.The samples are obtained within seconds,featuring a Cl-enriched surface that is unattainable via conventional thermal annealing.The best sample within the series shows a remarkable HER activity in both acidic and alkaline media with an overpotential of only-23 and-12 mV to reach the current density of 10 mA/cm^(2),highly comparable to that of the Pt/C benchmark.Theoretical studies based on density functional theory show that the excellent electrocatalytic activity is accounted by the surface metal-Cl species that facilitate charge transfer and downshift the d-band center.Results from this study highlight the unique advantages of MIH in rapid sample preparation,where residual anion ligands play a critical role in manipulating the electronic properties of the metal surfaces and the eventual electrocatalytic activity.Qiming Liu Bingzhang Lu Forrest Nichols Jeffrey Ko Rene Mercado Frank Bridges Shaowei Chen 2022SusMat2022,2,3:0
5反应性物种的电催化生成及其对微生物灭活的影响显示文摘控制水系统(包括废水、再生加工用水和饮用水)中的微生物繁殖对社会健康的生活环境至关重要.电催化反应产生的反应活性物种(RS)可以使微生物失活,从而为控制微生物生长提供了有效途径.本文概述了电催化反应产生RS及其应用于水消毒的最新进展,重点介绍了RS的选择性生产、微生物与RS的相互作用(包括RS作用机制和微生物对RS的天然反应),以及催化反应产生的RS用于微生物灭活的实际应用.本文还展望了基于RS的水电化学消毒的挑战和机遇以及未来可能的研究方向.Forrest Nichols Kenneth IOzoemena 陈少伟 2022Chinese Journal of Catalysis2022,43,6:0
