Effect of calcination on the C–H bond content. a Raman spectra of the ZrO2 CNAs before and after calcination at 300, 400, 500, and 800 °C for 1, 3, 5, and 12 h showing a reduction in the C–H content with increasing temperature. b The integral of the C–H Raman peaks for unprocessed and calcined CNAs with time, at different calcination temperatures. The plot shows a sharp decrease in the C–H content in the first 1 h of calcination followed by a plateau, at all temperatures
