沿着报道了用喷雾热分解法制备Fe（2）O（3）薄膜光阳极及其结构表征和在水的光电解中的应用。这些薄膜结合了联合收割机的良好性能（根据光电流密度测量）和优异的机械稳定性。喷雾热解方法的修改，如添加掺杂剂或结构导向剂和前体物质或载体溶剂的变化，对光电阳极的性能的影响的全面调查已经实现。由氯化铁前体溶液制备的光阳极获得最大的光电流，同时掺杂Ti（4+）（5%）和Al（3+）（1%）。用Zn（2+）掺杂也显示出希望，使起始电位阴极偏移约0.22 V。
The fabrication of thin-film Fe(2)O(3) photoanodes from the spray pyrolysis of Fe(III)-containing solutions is reported along with their structural characterization and application to the photoelectrolysis of water. These films combine good performance, measured in terms of photocurrent density, with excellent mechanical stability. A full investigation into the effects that modifications of the spray-pyrolysis method, such as the addition of dopants or structure-directing agents and changes in precursor species or carrier solvent, have on the performance of the photoanodes has been realized. The largest photocurrents were obtained from photoanodes prepared from ferric chloride precursor solutions, simultaneously doped with Ti(4+) (5%) and Al(3+) (1%). Doping with Zn(2+) also shows promise, cathodically shifting the onset potential by approximately 0.22 V.
