为解决工业蒽醌法合成过氧化氢(H2O2)的高能耗问题，研究人员开发了基于缺陷型SnSe纳米片的非均相催化体系。该研究首次实现在常温条件下仅以H2O和O2为原料、无需外加能量或助催化剂的H2O2合成，获得2.6 mmol g?1 h?1的产率，并实现50小时连续稳定生产，为绿色化学 ...

高中化学方程式配平在化学学习中非常重要，同学们需多加练习掌握配平技巧。以下是小编整理的化学方程式配平常见题目。 1化学方程式配平题目——经典例题 1、配平Al + Fe3O4 → Fe + Al2O3 第一步：配平氧原子 Al + 3Fe3O4 → Fe + 4Al2O3 第二步：配平铁和铝原子 8Al ...

光合成过氧化氢（H2O2）是太阳能的收集和转化的一种有效策略，但光合成H2O2的高效过程是由光生成的电子-空穴对重组导致的H2O2产率降低所驱动的，特别是在没有牺牲剂的情况下。基于此，厦门大学黄小青教授和韩佳甲助理教授、广东工业大学徐勇教授等人报道 ...

环氧丙烷(PO)是生产聚氨酯、聚酯、丙二醇等工业化学品的重要中间体。目前，生产PO的主要方法是氯醇法和共氧化法，这两种方法的加工过程都很复杂，而且容易产生多种有害副产品。以钛硅分子筛(TS-1)为催化剂，H2O2为氧化剂，甲醇(CH3OH)为溶剂的H2O2氧化生产PO ...

Abstract: While III-V photovoltaics are among the most efficient, they suffer from a high manufacturing cost. One of the methods of reducing this cost is through GaAs substrate reuse, with a promising ...

Chemical reactions involve the breaking and formation of chemical bonds between atoms, resulting in the formation of new substances. In order to determine the quantities of reactants and products ...
