该研究通过稳态测量、原位红外光谱和DFT计算，揭示了不同尺寸（1.8 nm和11.8 nm）PdχAu催化剂表面Pd原子的分布与反应性能的关系。结果表明，小尺寸催化剂因Pd原子暴露度更高、表面重构更显著，表现出更强的H2O2选择性及反应速率，且Pd-Au合金的电子结构和几何 ...

Two maize varieties, viz. Sartaj and Deccan, have been evaluated according to their responses to chromium (Cr) in terms of specific physiological and biochemical attributes. During the exposure to Cr ...

为解决CO2光催化还原选择性差与H2O2绿色合成难题，研究人员通过浸渍法（IMP）在CaTiO3（CTO）表面构建双功能Ag助催化剂体系，实现CO产率较光沉积法（PD）提升2倍并同步生成H2O2，为碳资源转化提供新策略。 全球气候危机与能源转型背景下，如何将温室气体CO 2 ...

华东理工大学李春忠和李宇航等人报道通过将羧基功能化的多壁碳纳米管作为底物为常规Ni-N4提供额外的O配位，合成包含由四个N和两个O原子（即N4-Ni1-O2）配位的单原子Ni位点的催化剂；N4-Ni1-O2催化剂上在200 mA cm-2电流密度下的阴极能量效率约为82%和H2O2法拉第效率 ...

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 ...
