Abstract The development of efficient and highly durable materials for renewable energy conversion devices is crucial to the future clean demand. Herein, cage‐like quasihexagonal structured platinum nanodendrites decorated over transition metal chalcogenide core (CoS 2 )‐N‐doped graphene oxide (PtNDs@CoS ‐NrGO) through optimized shape engineering structural control technology are fabricated. prepared electrocatalyst PtNDs@CoS ‐NrGO effectively used as anodic catalyst alcohol oxidation in...
Hydrogen produced using renewable energy from offshore wind provides a versatile method of storage and power-to-gas concepts. However, few dedicated floating electrolyser facilities currently exist therefore conditions the environment on hydrogen production cost efficiency remain uncertain. Therefore, this review focuses conversion electrical to hydrogen, water electrolysis located in areas. The challenges associated with remote locations, fluctuating power harsh are highlighted...
Zinc-air batteries are gaining popularity as viable energy sources for green storage technologies. The cost and performance of Zn-air mostly determined by the air electrodes in combination with an oxygen electrocatalyst. This research aims at particular innovations challenges relating to related materials. Here, a nanocomposite ZnCo2 Se4 @rGO that exhibits excellent electrocatalytic activity reduction reaction, ORR (E1/2 = 0.802 V), evolution OER (η10 298 mV@10 mA cm-2 ) is synthesized. In...
Hydrogen is envisaged to play a major role in decarbonizing our future energy systems. ideal for storing renewable over longer durations, strengthening security. It can be used provide electricity, heat, power long-haul transport, shipping, and aviation, several industrial processes. The cost of green hydrogen produced from via electrolysis dominated by the electricity used. Operating electrolyzers only during periods low prices will limit production capacity underutilize high investment...
Cerium oxide-anchored titanium carbide (CeO2-TiC) is realized as a potential inorganic filler when modifying the Nafion matrix of proton-exchange membrane fuel cell (PEMFC). A hydrothermal strategy was employed to synthesize CeO2-TiC high crystallinity mitigate problematic properties (PEM). with weight ratio 0.5, 1, 1.5, or 2% incorporated into form hybrid by adopting solution-casting procedure. Reinforcement owing presence TiC provides increased tensile strength PEM, and addition CeO2...
Direct alcohol fuel cells play a pivotal role in the synthesis of catalysts because their low cost, high catalytic activity, and long durability half-cell reactions, which include anode (alcohol oxidation) cathode (oxygen reduction) reactions. However, platinum suffer from CO tolerance, affects stability. The present study focuses on ultrafine Pt nanoparticles stabilized by flowerlike MoS2/N-doped reduced graphene oxide (Pt@MoS2/NrGO) architecture, developed via facile cost-competitive...
Cerium oxide–anchored amine-functionalized carbon nanotubes (CeO2–ACNTs) are applied as radical scavengers well solid proton conductors to realize hybrids with Nafion (Nafion/CeO2–ACNTs) for a proton-exchange membrane fuel cell (PEMFC) operating at low relative humidity (RH). Reinforcement due the existence of ACNTs offers good mechanical strength and conductivity hybrid, addition CeO2 mitigates chemical degradation hybrid. The Nafion/CeO2–ACNTs 20% RH is 12.2 mS cm–1, which 4 5 times better...
Tremendous developments in energy storage and conversion technologies urges researchers to develop inexpensive, greatly efficient, durable metal-free electrocatalysts for tri-functional electrochemical reactions, namely oxygen reduction reactions (ORRs), evolution (OERs) hydrogen (HERs). In these regards, this present study focuses upon the synthesis of porous carbon (PC) or N-doped (N-PC) acquired from golden shower pods biomass (GSB) via solvent-free synthesis. Raman spectroscopy, X-ray...
Highly active and durable hierarchical structure of ZnCo 2 S 4 grown on reduced graphene oxide nanosheet electrocatalysts for the green production hydrogen gas via water electrolysis.
Development of economical and efficient bifunctional electrocatalysts for the alkaline water/seawater electrolysis becomes essential industrial hydrogen production. Herein, we developed a rational design electrocatalyst with ultra-low (∼3.7%) loading iridium oxide nanoparticles anchored on hierarchical manganese sheet grown in reduced graphene (IrO2@MnO2/rGO) through cost-effective hydrothermal calcination route. The optimized IrO2@MnO2/rGO shows enhanced activity toward oxygen evolution...
