一般描述
氢氧化钾（KOH）又称苛性钾。它被用作许多含钾产品的重要前体。
应用
与碲粉结合，介导芳香族羰基化合物的吡那酮化反应。
氢氧化钾可用于：
- 作为碱，从胺和乙醇合成亚胺。
- 作为仲醇与伯醇β-烷基化反应的碱，无需任何过渡金属催化剂。
- 结合铝用于芳香醛的吡啶化和受阻酮的还原。
- 作为沉淀剂，采用改性水热法制备 MnZn 铁氧体纳米粒子（Mn0.8Zn0.2Fe2O4铁氧体纳米粒子）。

Water electrolysis offers a promising energy conversion and storage technology for mitigating the global energy and environmental crisis, but there still lack highly efficient and pH-universal electrocatalysts to boost the sluggish kinetics for both cathodic hydrogen evolution reaction (HER) and

Electroreduction of carbon dioxide to hydrocarbons and oxygenates on copper involves reduction to a carbon monoxide adsorbate followed by further transformation to hydrocarbons and oxygenates. Simultaneous improvement of these processes over a single reactive site is challenging due to the

The extracellular matrix (ECM) is a complex, spatially inhomogeneous environment that is host to myriad cell-receptor interactions that promote changes in cell behavior. These biological systems can be probed and simulated with engineered surfaces, but doing so demands careful control
