化工學(xué)院劉淑玲教授團(tuán)隊(duì)在電化學(xué)儲(chǔ)能及電催化領(lǐng)域取得重要進(jìn)展

近日，我?；瘜W(xué)與化工學(xué)院高性能功能材料與器件創(chuàng)新團(tuán)隊(duì)劉淑玲教授及王超副教授圍繞電化學(xué)儲(chǔ)能材料及電催化材料設(shè)計(jì)領(lǐng)域取得多項(xiàng)重要進(jìn)展，連續(xù)在Chemical Engineering Journal（IF = 16.744），Journal of Power Sources（IF = 9.794）, Applied Surface Science（IF = 7.392）, Electrochimica Acta (IF = 7.336)等國(guó)際知名期刊發(fā)表12篇研究論文。

這些研究工作主要涉及鋰離子電池/水系超級(jí)電容器高性能電極材料及水電解制氫新型催化劑的設(shè)計(jì)與開(kāi)發(fā)。針對(duì)鋰電電極/水系超級(jí)電容器電極材料面臨的容量低、穩(wěn)定性差的問(wèn)題，團(tuán)隊(duì)主要通過(guò)界面調(diào)控及優(yōu)化、異質(zhì)結(jié)構(gòu)設(shè)計(jì)等策略構(gòu)建高性能電極材料，提升了材料導(dǎo)電性，增加了儲(chǔ)離子位點(diǎn)，并抑制充放電過(guò)程中的不可逆相變，有效提升了材料儲(chǔ)能容量及循環(huán)穩(wěn)定性（Dual-layer carbon protected coaxial cable-like Si-based composites as high-performance anodes for lithium-ion batteries; A facile synthesis of Ni_0.85Se@Cu_2?xSe nanorods as high-performance supercapacitor electrode materials）。針對(duì)水電解制氫過(guò)程中，析氧反應(yīng)動(dòng)力學(xué)緩慢，需要極高過(guò)電勢(shì)的問(wèn)題，團(tuán)隊(duì)采用無(wú)定型/結(jié)晶態(tài)異相結(jié)構(gòu)設(shè)計(jì)、摻雜等策略，增加電化學(xué)活性位點(diǎn)數(shù)量，優(yōu)化析氧中間體吸附能，加速析氧反應(yīng)動(dòng)力學(xué)過(guò)程（Solvothermal preparation of nickel-iron phosphides hollow nanospheres derived from metal-organic frameworks for water oxidation reaction; Electrodeposited amorphous cobalt-nickel-phosphide-derived films as catalysts for electrochemical overall water splitting）。這些研究成果極大地?cái)U(kuò)展了高性能儲(chǔ)能材料/電催化劑的開(kāi)發(fā)，推動(dòng)了相關(guān)產(chǎn)業(yè)的發(fā)展。
