由于人类社会活动的加剧导致环境污染引发的气候变暖问题已成为21世纪人类亟待解决的最大难题。氢能，由于燃烧值高且清洁无污染，被认为是能从根本上解决这一难题的最理想的清洁能源之一。针对当前电催化水分解产氢过程中阳极氧化反应动力学缓慢及商业化贵金属电催化剂价格昂贵等问题，本项目提出基于电子自旋态调控和“热电子”耦合协同效应开发廉价的镍基硒化物催化剂。拟从镍基金属有机框架结构设计入手，结合柯肯达尔效应构筑镍基硒化物规则中空纳米结构，探索电子自旋态调控对反应中间产物吸附能的影响及其催化反应动力学的作用机制，明确激光诱导“热电子”效应中电荷转移对反应决策步骤及对活性位点催化活性的影响，最终开发出超低能耗镍基硒化物催化剂。本项目的预期研究成果将为电催化反应动力学的提升提供一种新的有效手段，为开发超低能耗且廉价的电催化剂指明方向。本项目也为低能耗催化剂制备及其进一步产业化提供了理论依据和实验指导。

With the upgrading intensive activates of humans, and in turn more and more serious environmental pollution and climate warming, humans’ living circumstance has become more and more serious, being the most serous problem of the 21st century that humans are facing. Hydrogen energy, possessing high combustion value and clean feature, has been regarded as one of the most promising clean energies, allowing people to fundamentally solve the common problems as well the largest challenge that humans are facing. Considering the slow catalytic reaction dynamic of oxygen evolution at the anode and the high cost of the commercial previous metal-based catalysts, we aim to explore nickel-based selenides based on the synergistic effect of spin states and “hot-electrons” towards electrocatalytic applications. In this project, by designing nickel-based metal-organic framework (MOF) together with the Kirkendall effect, hollow structured nickel-based selenides with regular shape could be realized, and the following aims are desired to be achieved: 1) understand the influence of spin states of transition metals on the adsorption energy of reaction intermediates, and unveil its impact to the kinetics of catalytic reaction; 2) reveal the rate-determination step and activities of the catalytic active sites caused by the “hot electrons” and its transfer information during the involved laser irradiation. With these efforts, it makes fabrication of nickel-based catalysts with ultra-low energy consumption being possible. We propose that our project will provide a new strategy for boosting the kinetics of catalytic reactions, and shed light on the ways for the exploration of low-cost electocatalysts with ultra-low energy consumption. Additionally, our project not only provides evidence for the configuration of nanoarchitectured electrocatlysts toward low energy consumption, but also could accelerate its industrialization process.
