Terwards, water within the mixture was removed at 110 C; the resultant sample was dried at 110 C for 12 h and calcined at 800 C for four h in air forcatalysts 2021, 11,slowly formed and ultimately a hydroxide strong layer was formed around the outer surface of the SBA-15 during 24 h of reaction. Afterwards, water within the mixture was removed at 110 ; the For the reason that the ureawas dried at rate for 12 h and calcinedNi(OH)2 precipitateair for resultant sample hydrolysis 110 is fairly slow, the at 800 for 4 h in was gradually formed and finally a hydroxide solid layer was formed then reducedsurface 2 atthe acquiring NiO/SBA-15 (equation four).
