The development of low‐cost single‐atom electrocatalysts for oxygen reduction reaction (ORR) is highly desired but remains a grand challenge. Superior to the conventional techniques, a microwave‐assisted strategy is reported for rapid production of high‐quality Fe/N/C single‐atom catalysts (SACs) with profoundly enhanced reaction rate and remarkably reduced energy consumption. The as‐synthesized catalysts...
The repair of bone defects caused by osteosarcoma resection remains a clinical challenge because of the tumor recurrence and bacterial infection. Combining tumor and bacterial therapy with bone regeneration properties in bone implants is a promising strategy for the treatment of osteosarcoma. Here, a layer of MgO/FeOx nanosheet is constructed on the Ti implant to prevent tumor recurrence and bacterial...
Photocatalytic CO2 reduction by solar energy into carbonaceous feedstock chemicals is recognized as one of the effective ways to mitigate both the energy crisis and greenhouse effect, which fundamentally relies on the development of advanced photocatalysts. Here, the exploration of porous microrod photocatalysts based on novel NiCoO solid solutions derived from bimetallic metal–organic frameworks...
