Water electrolyzer is crucial for producing clean hydrogen, but the traditional approach faces challenges owing to the oxygen evolution reaction (OER) slow kinetics at the anode. Hybrid water splitting replaces the OER with the oxidation of an organic molecule to enhance hydrogen production along with value-added products. The scarcity of affordable and highly effective catalysts remains a major challenge. MXene, a 2D nanomaterial, has gained substantial attention for its enviable properties, for instance high conductivity, hydrophilicity, and substantial surface area. This review discusses experimental methods for synthesizing MXene and MXene-based nanocomposites. Furthermore, the small molecules oxidation such as benzyl alcohol, methanol, ethanol, urea, hydrazine, furfural, and formic acid as alternatives to the oxygen evolution reaction is examined. Finally, an understanding of imminent research and the development of MXene-associated materials in electrocatalytic applications are presented.
水电解槽对于生产清洁氢气至关重要，但传统方法由于阳极析氧反应（OER）动力学缓慢而面临挑战。混合水分解通过有机分子氧化替代OER，以提高氢气产量并同时生产增值产品。缺乏经济实惠且高效的催化剂仍然是一个重大挑战。MXene作为一种二维纳米材料，因其令人羡慕的特性，如高导电性、亲水性和大表面积，而备受关注。本文综述了合成MXene及基于MXene的纳米复合材料的实验方法。此外，还研究了诸如苯甲醇、甲醇、乙醇、尿素、肼、糠醛和甲酸等小分子氧化作为析氧反应替代物的情况。最后，介绍了对MXene相关材料在电催化应用中紧迫研究和发展的理解。
