利用太阳能将CO_(2)光转化为化学燃料是前沿研究的热点.当前,科研的重点在于开发和优化各类光催化材料的性能.异质结构不仅用于增强无机半导体催化剂的活性,而且用于金属-有机框架(MOFs)光催化剂的构建.随着异质结技术的不断进步,新的相结概念应运而生.尽管关于无机半导体中的相结研究已取得一定进展,但是MOFs相结结构的探索尚处于起步阶段.本文中,我们成功设计并构建了一种具有卓越光催化CO_(2)还原性能的MOFs相结杂化材料.这种材料由具有高度连接性的卟啉配体(TCPP-Ni)与Zr6团簇紧密结合而成,在溶剂热反应条件下,PCN-222-Ni能够快速且均匀地成核.通过精准调控调节剂的用量,我们实现了同分异构体PCN-224-Ni在类似条件下较慢的晶体形成过程.最终制得的P@P杂化材料展现出高表面积、多孔性和卓越的结晶度.由于PCN-222-Ni和PCN-224-Ni之间的带隙匹配,光生载流子的分离和迁移得以促进,从而使P@P杂化材料展现出卓越的光还原CO_(2)性能.这一重大突破不仅标志着MOFs相结结构研究的重大进展,还拓宽了MOFs相结在CO_(2)光转化领域的应用前景.
