“…From 2010, CDI research focused more on electrode characteristic [120] and operation‐based research [143] . We even went as far as using CDI operation for electrode fabrication [144] . With the continuous progress in CDI, our group shifted and centered on electrode fabrication and development [56,68,88,89,145] .…”

Capacitive deionization (CDI) is a potential technology to provide cost efficient desalinated and/or softened water. Several efforts have been invested in the fabrication of CDI electrodes that not only has outstanding performance but also high chance of large scalability. In this personal account, the different techniques in developing carbon‐based materials are presented together with its actual effect on the surface and electrochemical properties of carbon. The categories presented are based on the studies done by the Electrochemical Reaction and Technology Laboratory, the Ertl Center, different research groups in South Korea, and selected papers from the past three years. Our perspective about research gaps and prospects are also included with the aim to increase interest for CDI research.

“…107 Lee reported a Fe-B/C cloth pre-catalyst by electrochemical adsorption techniques. 108 The hydrogen generation rate using the Fe-B/C cloth pre-catalyst can achieve 813 mL min −1 g −1 at room temperature. The Fe-B/Ni foam catalyst was also prepared by the same group for hydrogen generation from NaBH 4 in a mixture solution of H 2 O and CH 3 OH.…”

“…Nevertheless, the high cost of noble metals has made them less attractive, especially for industrial applications [17]. Besides noble metals, transition metals and their alloys (e.g., Ni, Co, Fe, Si, Co-B, Ni-Fe-B, and Co-Mo-Pd-B) are other groups of metal catalysts that have attracted more interest in recent years due to their affordable cost and good catalytic activity [18][19][20][21][22][23][24]. However, the low chemical stability and agglomeration during the process as a result of the high surface energy of catalyst powder are the main limitation of transition metal catalysts [25].…”

Rice husk is a massive byproduct of the agricultural sector, but less effort has been paid for its recycling.In this study, ultrasound-assisted inorganic treatment with HNO 3 , H 2 SO 4 , and H 2 O 2 was adopted to modify rice husk as a biomass catalyst. The activity of produced biomass catalyst was assessed in hydrogen production through the hydrolysis of sodium borohydride in an alkaline solution. The characterization of as-prepared biomass catalysts revealed that HNO 3 was an e cient agent to protonate the surface of rice husk and make active sites available for the hydrolysis reactions. In addition, ultrasound-assisted HNO 3 treatment caused a constructive effect on the structural property of rice husk and increased the surface area from 1.9 m 2 .gr − 1 to 17 m 2 .gr − 1 and pore volume from 0.45 cm 3 .gr − 1 to 3.9 cm 3 .gr − 1 . According to optimum synthesizing conditions (45 wt% HNO 3 and 10 min ultrasonication), ARH-N 45 -10 could produce 745 ml.gr − 1 hydrogen from the alkaline solution of NaBH 4 at ambient conditions. Based on the kinetic study, the catalytic hydrolysis of NaBH 4 by modi ed rice husk followed rst-order kinetic concerning the NaBH 4 per xed NaOH ratio. Moreover, the thermodynamic analysis indicated that hydrolysis of NaBH 4 and formation of hydrogen on the modi ed rice husk is an endothermic and spontaneous reaction, where the hydrogen generated at 55˚C (5280 ml.gr − 1 ) was seven times more than that at ambient temperature and also activation energy was calculated 57.68 kJ.mol − 1 from Arrhenius plot.
