一般描述
碳酸钙是一种无机化合物，难溶于水，但极易溶于稀酸。它在材料科学中起着至关重要的作用，特别是在太阳能电池、电池和超级电容器的发展中。在太阳能电池中，它作为钙钛矿层的前体材料，提高了钙钛矿太阳能电池的稳定性和性能。此外，碳酸钙被用于电极生产，作为阴极或阳极材料的导电添加剂，从而提高电池的整体性能和耐用性。
应用
碳酸钙可用作：
- 在从煤焦油沥青制备多孔石墨碳材料的过程中，使用一种绿色合成方法，其中涉及到三种关键组分：模板、石墨化催化剂和活化剂。
- 以二氧化钛（TiO2）为原料，采用溶胶-凝胶法制备钛酸钙（CaTiO3）钙钛矿材料。钛酸钙可用于制造大规模、低成本和可持续的太阳能电池。
- 催化剂有助于提高燃料电池的性能和耐久性，从而促进清洁能源技术的发展。
