Machine learning, new artificial intelligence technology, has recently been used various fields owing its ability rapidly analyze large amounts data guide material synthesis. Consequently, we constructed machine learning model based on previously reported experimental guided fabrication boron-doped ORR. The achieved catalytic performance exceeded most ORR terms selectivity (90-95% broad potentials 0.30-0.68 V vs reversible hydrogen electrode), stability (maintaining over 90% 12 h), yield (3450 mmol gcatalyst-1 h-1), Faraday efficiency (over 90%).
