The collected chicken bones were first treated with boiled water for about 20 min and then dried in the sun rays for several days. The washed bones were dried in oven at 110 C for 6 h and later ground to fine powder using agate mortar. The powder material was calcined in the furnace at 800 C, 900 C and 1000 C for 4 h. The synthesized catalysts are represented as C800, C900 and C1000 according to the calcination temperature.
