“…Nowadays, energy and chemicals are produced from fossils source. Energy and environmental problems elevated by the usage and potential depletion of fossil fuels stimulate research on the new energy sources [1][2][3][4][5][6]. The increase in population and industrial development has accelerated the exploration of renewable clean energy resources such as hydrogen energy [7][8], solar energy [9][10], and biodiesel [11].…”

The research on the use of coconut husk as a solid catalyst for transesterification reaction of Cerbera manghas oil into biodiesel has been done. The aim of this study is to investigate the performance of coconut husk ash for biodiesel production from Cerbera manghas seed oil. Coconut husk is prepared by burning in air to obtain potassium oxide as active phase. The coconut husk is analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD spectrum shows that the peak characteristics of potassium oxide can be observed in the diffractogram. The particle size of the catalyst ranging from 1 - 3 μm with pentagonal structure. The coconut husk ash solid catalyst is used in the transesterification reaction of Cerbera manghas oil in a batch reactor. Biodiesel yield of 88.6% can be achieved over coconut husk ash catalyst, using a 10 wt.% of catalyst, reaction temperature at 3 hours, and a methanol-to-oil ratio of 6: 1. This solid catalyst can be separated easily from the reaction system and not soluble in methanol or methyl esters. The coconut husk ash catalyst is high potential to be developed as one of the solid catalysts to convert Cerbera manghas oil to biodiesel.

“…These results are consistent with the XRD patterns presented above as well. Based on previous research [ 46 ], good catalytic activity is enabled by the preservation of the support material after catalyst preparation. In addition, the metal oxide species must be highly distributed upon the surface of the support.…”

In this study, glycerol as an abundant green feedstock was used as a hydrogen source to investigate the reaction of water-glycerol solution decomposition by microwave-assisted catalytic to produce hydrogen over NiO/zeolite catalyst. The catalyst was prepared by inception wetness and then characterized through X-ray diffraction (XRD), scanning electron microscopy (SEM), Energy diffraction X-ray (EDX), and transmission electron microscope (TEM) measurements. The conversion process of glycerol into hydrogen was performed in a fixed-bed microwave-assisted reactor. Effect of microwave power, NiO content, and feed flow rate (FFR) on glycerol conversion and hydrogen selectivity were studied. The results of XRD and EDX measurement showed that NiO crystalline exists on the catalyst sample. The particle size of NiO/zeolite was determined in the range of 30–300 nm, and the particle was found well dispersed on the zeolite surface as confirmed by TEM. Furthermore, the maximum conversion rate can achieve about 96.67 %, while the highest hydrogen production was found up to 73.5 % with the condition of 20% of NiO as an active site on natural zeolite. It was found that the NiO content of 20% gave the best glycerol conversion at the microwave power of 600 W and FFR 0.5 ml/min. Microwave-assisted catalytic irradiation of glycerol appears to be a promising candidate for the production of H 2 from an aqueous glycerol solution.

“…NaTaO 3 is also reported for photocatalytic H 2 evolution with the modifications performed by doping and composite formation. − Ivanova et al have studied the effect of different noble metals (Pt, Au, and Rh) and metal oxide (NiO, CuO, Ag 2 O, RuO 2 , and CoO) cocatalysts on the photocatalytic activity of La-doped NaTaO 3 toward H 2 and O 2 evolution from water . In the reactions, overall water splitting was not observed when a single cocatalyst was used with La-NaTaO 3 .…”
