Amine-functionalized biochar as a green and recyclable nanocatalyst for the efficient synthesis of 1,8-naphthyridine and 2-amino-4H-chromene derivatives
Biochar is a renewable carbon-based material derived from biomass resources, which has attracted widespread attention due to its low production cost, environmental sustainability and high surface modification and functionalization capabilities. However, its potential application as an effective catalyst, especially for...
