This is achieved by utilizing heterogeneous atoms on the surface that exhibit distinct adsorption behaviors for hydrogen and hydroxyl, thereby accelerating the dissociation of water and mediating the adsorption of hydrogen intermediates required for molecule formation. The monolithic nanoporous multi-metal NiFeCoCuTi alloy electrode displays remarkable alkaline HER and OER electrocatalysis, exhibiting low overpotentials of 48.7 and 264.2 mV, respectively, to deliver a current density of 10 mA cm⁻². Furthermore, it demonstrates exceptional stability for over 100 h in 1 M KOH electrolyte. The exceptional qualities of nanoporous NiFeCoCuTi alloy electrodes make them a highly desirable option for utilization as the cathode and anode material in water electrolysis, which produces hydrogen.

On the other hand, the penetration of fuel cell vehicles in transportation sector is increasing. The role of hydrogen refuelling stations is to inject hydrogen into fuel cell vehicles. A hydrogen refuelling station may absorb its required electricity from an energy hub. The operational planning of the microgrids with hydrogen refuelling station-integrated energy hubs has not been addressed before; therefore, the main goal of this research is to develop a hierarchical stochastic framework for operational planning of isolated microgrids with hydrogen refuelling station-integrated energy hubs, considering the uncertainties. In a hierarchical framework, the players are not obliged to submit their models to a central agent, so the privacy of players is preserved; moreover, it is computationally inexpensive. Mixed-integer linear programming models are used for hydrogen refuelling stations and energy hubs, while a mixed-integer quadratic programming model is used for modeling microgrid. CPLEX and GUROBI solvers are respectively used for solving the developed models. SCENRED module is used for scenario reduction. The studied microgrid is a renewable-rich 69-bus radial network. The findings approve the efficiency of the proposed methodology.

In this study, a topology optimization (TO) model is developed to optimize the distribution of porous catalysts in microreactors to improve the conversion from ammonia (NH₃) to hydrogen (H₂), which considers the fully coupled processes of flow, heat transfer, mass transport and reaction with variable physical properties. Dual objectives of reducing the flow resistance and decreasing the average temperature of the microreactor are employed for the TO model to generate innovative structures. The effects of different weight coefficients, input heat, volume fractions of the catalyst, and microreactor sizes on TO structures are explored. As validated by three-dimensional (3D) simulations, the TO microreactor can obtain lower pressure drop, lower average temperature, and higher NH₃ conversion compared to traditional microreactors. At a weight coefficient of 0.95 and a catalyst volume fraction of 0.6, the optimized microreactor shows a 5.78% increase in NH₃ conversion, an 18.05% decrease in pressure drop, and a 4.26% decrease in average temperature compared to the traditional straight-channel microreactor. Finally, it is interesting to find that all TO structures generated are characterized by the gradually decreased size of the catalyst block along the flow direction which allows more NH₃ to be decomposed at higher temperature regions with higher reaction rates, leading to higher conversion.

Herein, the recent advances in the most versatile and emerging design strategies as viable routes to overcome inadequate sunlight conversion efficiency in photocatalytic applications are discussed. This review first introduces various design strategies to expand the spectral response of photocatalysts, which extend light harvesting toward a large fraction of the solar spectrum, and dictate how photons' high potential is utilized to generate electron-hole pairs. We then discuss efficient strategies to obtain high separation of electron-hole pairs, and—when compared to high recombination loss of charge carriers—increased lifetime plays a pivotal role in promoting sunlight conversion. Furthermore, to elucidate the relationship between charge kinetics and sunlight conversion, the next section includes an in-depth discussion of various strategies, which clarify that charge migration and subsequent utilization can be enhanced by manipulating charge kinetics.
