Mesoporous carbon nanospheres are produced from biowaste, Allium cepa peels, well known as “onion” dry peels using the catalyst-free pyrolysis method. The synthesis process involves an unusable bio-precursor that is accumulated in millions of tons per year. The obtained materials show nanosphere mor...
