By far Pt stands for the best ORR catalyst, however, considering the scarcity and high cost, it is imperative to further improve its catalytic activity and atomic efficiency to reduce the loading amount. In view of the key issues, this review concentrates on recent advances on developing high-performance Pt-based nanocatalysts for ORR. The catalytic ORR mechanism was first described, followed by presenting the major principles to regulate ORR activity involving ligand effect and geometric effect. Guided by the principles, typical design strategies of Pt-based nanocatalysts were detailedly summarized, with emphasis on increasing intrinsic activity of single active site and electrochemical active surface area. We finally concluded by providing the remaining challenges and future directions in this field.</p></div>","PeriodicalId":100036,"journal":{"name":"Advanced Sensor and Energy Materials","volume":"2 1","pages":"Article 100022"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49713244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These nanocomposites are typically prepared by conventional pyrolysis that is tedious and energy-intensive. Herein, we report the ultrafast preparation of cobalt/carbon nanocomposites by magnetic induction heating (MIH) of metal organic frameworks within seconds under an inert atmosphere. The resulting samples consist of cobalt nanoparticles encapsulated within defective carbon shells, and effectively catalyze oxygen evolution reaction (OER) in alkaline media. Among the series, the sample prepared at 400 A for 10 s exhibits the best OER performance, needing a low overpotential of +308 mV to reach the current density of 10 mA cm<sup>−2</sup>, along with excellent stability, and even outperforms commercial RuO<sub>2</sub> at high overpotentials. This is ascribed to the charge transfer between the carbon scaffold and metal nanoparticles. Operando X-ray absorption spectroscopy measurements show that the electrochemically produced CoOOH species is responsible for the high electrocatalytic performance. The results highlight the unique potential of MIH in the development of effective nanocomposite catalysts for electrochemical energy technologies.</p></div>","PeriodicalId":100036,"journal":{"name":"Advanced Sensor and Energy Materials","volume":"2 1","pages":"Article 100046"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49713246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
