The Catalyst Loading Effects on the Feed Rate of NaBH4 Solution for the Hydrogen Production Rate and Conversion Efficiency

Abstract

The research in this study focused on the operating parameters for a high efficiency hydrogen production rate system, with the aim to design a hydrolysis of the NaBH4 hydrogen production module for lightweight and efficient hydrogen production and conversion. The experiment used a reactor, where the reaction volume was about 12 mL. The parameters on the feed rate of the NaBH4 solution and the catalyst loading for the hydrogen production rate and conversion efficiency were investigated. The catalyst is sufficient to allow the release of hydrogen in the 1 g/min solution, but the efficiency of hydrogen production at high flow rates has been shown to be low in previous studies. Therefore, the aim is to increase the catalyst to improve the reaction efficiency in this study. The results show that at the high temperature reaction condition, solid NaBO2 will not generate on the catalyst surface to influence the hydrogen production rate when using the five pcs catalyst. When the reaction temperature was 108 °C, the average hydrogen production rate was 1.72 L/min, and the conversion efficiency was 91.2%.

Effect of Phosphorus-Doped Phase-Modulated WS2 Nanosheets on CdS Nanorods for Highly Efficient Photocatalytic Hydrogen Production

“…For instance, the number of active sites accessible for the photocatalytic reaction may be limited by an inadequate dosage of catalyst, which would result in slower rates of hydrogen evolution, and overdosing of catalyst can result in surface saturation, where all possible active sites are occupied. Also, the catalysts may aggregate, decreasing the total active surface area and impeding the photocatalytic reaction. , Here, we demonstrate that the optimal amount of photocatalyst to employ for hydrogen synthesis is 1 mg; any amount over this limit will result in a drop in the rate of hydrogen production Figure S8. Moreover, the choice of the hole-scavenger medium affects the rate of photocatalytic hydrogen production.…”

Preparation of highly efficient NiB catalyst via triton‐stabilized for alkaline NaBH 4 hydrolysis reaction

“…16 Leu et al examined the effect of the feed rate of the NaBH 4 solution and the catalyst loading on the hydrogen production rate and conversion efficiency. The average hydrogen production rate and conversion efficiency were found to be 1.72 L min −1 and 91.2% when the reaction temperature reached to the 108 C. 17 However, in the literature, noble metals such as platinum (Pt), 18 ruthenium (Ru) 19 and palladium (Pd) 20 are widely used in the hydrolysis of NaBH 4 . These catalysts restrict their use in a number of applications due to their high costs despite their high activity.…”
