Web31 aug. 2024 · Oxides are chemical compounds with one or more oxygen atoms combined with another element (e.g. Li 2 O). Oxides are binary compounds of oxygen with another element, e.g., CO 2, SO 2, CaO, CO, ZnO, BaO 2, H 2 O, etc. These are termed as oxides because here, oxygen is in combination with only one element. Based on their acid-base … Web10 apr. 2024 · Engineering the local environment surrounding an active site at liquid-solid interfaces is of importance in organic synthesis and industrial chemical production. Here, Li et al. assess the cooperative roles of water and metal oxide interfaces in the selective hydrogenation of bonds over cobalt-based catalysts, revealing that small amounts of …
