The development of photo-anode film for photo-electrochemical (PEC) reactor producing hydrogen (H2)
Muhammad Hafiz, Abdul RahimThe world now uses energy at a rate of 13 TW. However, demand for energy will double by 2050 and more than triple by the end of the century. Petroleum as an energy source is unsustainable because it tied to global warming, ... -
Effect of dolomite on pyrolysis of rice straw
Razi, Ahmad; Nasrul, Hamidin, Dr.; Umi Fazara, Md. Ali, Dr. (2013)A study of catalytic pyrolysis on rice straw was carried out in a fixed-bed reactor. The objectives were to determine the effect of dolomite catalyst on the distribution of product yield and bio-oil characterization. The ... -
H2-PEC-Hematite 'reactors for tomorrow's energy': H2 production via photo-electrochemical reactor
Umi Fazara, Md. Ali, Dr. (Universiti Malaysia Perlis (UniMAP)School of Environmental Engineering, 2014-05)75% of global electrical energy production involves fossil fuel combustion, resulting in the detrimental effects of CO2, SOx and NOx emissions (Fig, 1). Obviating such effects and fossil fuel depletion are the main drivers ... -
