In2O3-CuInS2 composite rodlike catalyst as well as preparation method and application thereof

The invention discloses a preparation method and application of an In2O3-CuInS2 composite rod-like catalyst, and belongs to the technical field of catalysts. The method specifically comprises the following steps: 1, mixing an indium source with DMF and TPA, and synthesizing In-MOF at 120-140 DEG C; 2, calcining the In-MOF under the protection of Ar gas for 2 hours to obtain In2O3; and 3, mixing In2O3 with a copper source, an indium source and a sulfur source, and carrying out alcohothermal synthesis to obtain the In2O3-CuInS2 composite rod-like catalyst. The prepared catalyst is of an In2O3-CuInS2 self-assembled hollow rod-like structure, shows efficient nitrogen fixation performance, and has wide application potential. 本发明公开了一种In2O3-CuInS2复合棒状催化剂的制备方法与应用，属于催化剂技术领域。本发明具体按照以下步骤进行：第一步将铟源和DMF、TPA混合，在120℃-140℃合成In-MOF；第二步将In-MOF在Ar气保护下煅烧2h得到In2O3；第三步将In2O3与铜源、铟源、硫源混合醇热合成In2O3-CuInS2复合棒状催化剂。所制备的催化剂呈In2O3-CuInS2自组装中空棒状结构，其表现出高效的固氮性能，具有广阔的应用潜能。
