“…Comparison of the present energy efficiency to Demir et al’s results, the energy efficiencies were found to be 2.92 and 2.10%, respectively. The present hydrogen production rates are higher than Demir’s case because of the current active area is around triple times compared to Demir’s case.…”

A unique meshy dome-type photoanode design is investigated to utilize the available light at any angle of the sunbeams during daytime due to its specific configuration. The configuration of the working photoanode aims to harvest the maximum available sunlight by increasing the illuminated area. The mesh content allows the light beams to spread inside the dome electrode to increase the absorbed light at the different angles of the sunbeams during the daytime. The present dome mesh cathode and photoanode are manufactured from cheap materials such as titanium and stainless steel. The stainless-steel photoanode is deposited by titanium dioxide using the sol–gel dip-coating method. The current electrodes are placed in a potassium dioxide solution of 0.25 M and tested under artificial light at two conditions, including 45° tilted and vertical light. The current experimental results show that the greatest photocurrent density obtained is 5.05 mA/cm2. The maximum hydrogen production rates obtained under the tilted and vertical-light conditions are 14.01 and 14.36 μg/s, respectively. The highest overall energy efficiency obtained at the vertical-light condition is 2.92%. The enhancement of the hydrogen production rate fluctuates in the range of 75–80% that occurs with tilted light, compared with the enhancement under vertical-light conditions.

“…Although water electrolysis constitutes a small part of the world hydrogen production, its tendency is increasing day by day because of zero carbon emissions 1‐3 . The purity of hydrogen produced by the water electrolysis is very high, the method is simple and it ensures the development of the fuel cell technology 4‐9 . Beside these remarkable properties, the main disadvantage of the hydrogen production by the water electrolysis is the high energy consumption and consequently the low catalytic activity.…”

Summary In this work, we introduced a green methodology for the production of palladium (Pd) decorated reduced graphene oxide (rGO), using an endemic plant of Onosma malatyana Binzet (OMB) root extract for the first time and used it as an electrocatalyst for hydrogen evolution reaction (HER) in aqueous acidic media. Benefiting from the synergetic effect between rGO and Pd nanoparticles, the as‐prepared bio‐reduced GO/Pd (bio‐rGO/Pd) nanocomposite exhibits a remarkable performance towards HER when the results compared with the bio‐rGO and bio‐rPd nanocomposite. The HER overpotential at a current density of 10 mA cm−2 for bio‐rGO/Pd was only 0.17 V. The Tafel slope of the bio‐rGO/Pd nanocomposite film obtained from the HER polarization curves exhibits 154 mV dec−1, showing that the process is limited by the Volmer reaction step. In addition, the bio‐rGO/Pd nanocomposite electrode also showed an outstanding stability after a long‐term potential cycling measurement. It possesses a high synergetic effect, low charge transfer resistance and considerable electrochemical surface area. The all obtained results demonstrated that the bio‐rGO/Pd will be a promising green synthesized HER catalyst.

“…Hence, it is of the utmost importance drawing more attention to the sustainable development of water treatment and ES systems, in order to tackle the issue of energy and water scarcity. Systems based on RES can be part of the solution, if they are combined with another ones, due to their intermittent nature [14]. FF (oil, coal and gas), hydro and nuclear power, and RES (e.g.…”

“…50% of global H2 production is currently obtained by natural gas steam reforming, around 48% from other FF (30% from oil/naphtha reforming, 18% from coal gasification), 3.9% from electrolysis and 0.1% from other processes. H2 is widely used in various industries, such as petrochemical and petroleum refining processes, fertilizers, fuel cell stacks and electric vehicles [2,[14][15][16][17]. Despite the growing interest in H2 as an energy carrier, its main uses continue to be in petroleum refining, ammonia production, metal refining and electronics manufacturing, with an average worldwide consumption of about 40 million tonnes.…”

Due to its highest gravimetric energy density, H2 has been regarded as the preferred cleanenergy carrier, with potentially environmentally-friendly production through the solarassisted WS. Since human activities generate enormous amounts of WW, H2 production from this new resource has gained attention as an emergent technology. This paper addresses the most relevant and current aspects of H2 production from WWEL, and electricity generation from RES. In this sense, the state of art of H2 production, especially from WS, is presented here, as well as the main approaches to electricity generation from RES, with the greatest potential for viability. A new approach on this matter, which is part of the work that is being developed by the authors of this study, was also herein presented.
