Niobium and antimony doped tin oxide loose-tubes decorated with Pt nanoparticles present outstanding mass activity and stability, exceeding those of a reference carbon-based electrocatalyst. Physico-chemical characterisation and in particular X-ray photoelectron spectroscopy demonstrate that this observation can be ascribed to the strong metal–support interaction promoting electroactivity and Pt anchoring on doped metal oxide supports.

强大的金属-载体相互作用提高了掺杂金属氧化物上Pt电催化剂的活性和稳定性†

用Pt纳米粒子装饰的掺铌和锑的氧化锡松散管具有出色的质量活性和稳定性，超过了参考碳基电催化剂的质量活性和稳定性。物理化学特征，特别是X射线光电子能谱表明，该观察结果可归因于强的金属-载体相互作用，从而促进了电活性和Pt锚定在掺杂的金属氧化物载体上。
