一般描述
碳酸氢铵是铵离子的碳酸氢盐。除了作为氨的来源外，它还通常用作温和的碱。氨的碳酸氢盐呈颗粒状晶体，易溶于水。在催化剂的合成中，使用碳酸氢铵。
应用
碳酸氢铵可用作：
- 作为矿物燃料，采用溶胶-凝胶燃烧法制备氧化铝-氧化锆纳米粉体。
- 沉淀剂，用于合成 γ-Al2O3 样品（γ-Al2O3-1），用于从水溶液中去除氟化物。

A highly efficient, reversible hydrogen storage-evolution process has been developed based on the ammonium bicarbonate/formate redox equilibrium over the same carbon-supported palladium nanocatalyst. This heterogeneously catalyzed hydrogen storage system is comparable to the counterpart homogeneous systems and has shown fast
