DRM performance and carbon deposition analysis over Ni/HAP and Ni/HAP-Ce samples. a CO2 conversion during DRM over HAP and c HAP-Ce supported different Ni catalysts. Conditions: T = 750 °C, CH4/CO2/He = 10/10/30, total flow = 50 mL min–1 (GHSV = 60,000 mL h−1 gcat−1), inset is Raman spectra of spent 0.5Ni1/HAP and 10Ni/HAP after reaction at 750 °C and STEM image of 0.5Ni1/HAP after 7 h reaction; b–d TGA-MS and TGA profiles of various catalysts after different reaction times on-stream at 750 °C
