Residuals have rarely been granted attention when employing a hydrothermal approach to prepare binder-free supported catalysts. Using Ni foam supported NiCo2O4 catalyst for oxygen evolution reaction as an example, it was found that the catalytic activity of NiCo2O4 from the residuals loaded on glass carbon is comparable to Ni foam supported NiCo2O4, while the specific activity and turnover frequency value of the former catalyst are many times higher than that of the supported catalyst. In view of sustainability and green development, residuals should be given more attention when catalyst is prepared using the hydrothermal fabrication approach.
在采用水热法制备无粘结剂负载型催化剂时，很少有人关注残留物。以 Ni 泡沫负载 NiCo2O4 催化剂为例，用于析氧反应，发现负载在玻璃碳上的残留物所制备的 NiCo2O4 的催化活性与 Ni 泡沫负载 NiCo2O4 相当，而前者的比活性和周转频率值是负载型催化剂的许多倍。鉴于可持续性和绿色发展，在采用水热法制备催化剂时，应该更加关注残留物。
