“…138,139 Magneto-electrochemistry has recently become a novel strategy to intensify the electrochemical process, such as water splitting, CO 2 reduction and fuel cells. 140 The corresponding mechanism depends on the modulation of mass transfer and reaction kinetics, while the fundamental principles are multifarious, including the magnetothermal effect, magnetohydrodynamic (MHD) and micro-MHD effects, Kelvin force effect, Maxwell stress effect, and the spin selectivity effect mechanism. 141 For the CO 2 RR, the representative work is performed by Pan et al based on the spin selectivity effect (Fig.…”

“…A Monkhorst–Pack scheme of 9 × 9 × 1 k -point grid was used. SCF cutoff was set at 1 × 10 –6 , and the energy value cutoff for geometry optimization was set at 1 × 10 –9 . , Geometry optimization was performed initially prior to DOS calculations. Figure shows that the density of states plots for the different copper ferrite unit cells with varying occupancy levels.…”

Solvothermal Etching-Assisted Phase and Morphology Tailoring in Highly Porous CuFe₂O₄ Nanoflake Photocathodes for Solar Water Splitting

Improvization of synthetic strategies for designing novel nanostructures with desirable tailored morphology for efficient solar energy utilization has been at the focus of research on photoelectrochemical water splitting. This work presents a novel fabrication technique comprised of photocathodes comprised of highly porous copper ferrite nanoflake arrays by low-temperature surfactant-assisted solvothermal phase change induced temperature-controlled etching process. Solvothermally predeposited hematite on FTO glass was treated by a second solvothermal step, whereby surfactant-capped Cu2+ ions were forcibly impregnated into the hematite lattice at varying temperatures, resulting in phase change along with a drastic change in nanostructure morphology and crystal phase without the formation of any copper oxide surface impurities causing a temperature-dependent control over the degree of spinel inversion (δ), the underlying electronic properties of which were analyzed using DFT calculations. Analysis of photoelectrochemical (PEC) performance of the fabricated photocathodes was performed under A.M 1.5 G simulated solar illumination under a linear voltage sweep using a potentiostat with the three-electrode setup using 1 M H2SO4 aqueous solution as an electrolyte. The photocathode with δ = 0.77 exhibited the highest photocurrent density of −0.139 mA/cm2 at 0 V (vs RHE) and −2.57 mA/cm2 at −1 V (vs RHE). It also exhibited the highest IPCE % of 18.7%, which was higher than that of the photocathode with δ = 0.71, because of the depreciatory effect of high temperature on morphology, thereby emphasizing the precise synergistic influence of phase and morphology control simultaneously upon PEC performance. This work should inspire further research in developing unique wet chemical synthesis strategies for designing porous and highly ordered impurity-free nanostructures with temperature-dependent phase control for photoelectrode applications.

“…Traditional energy harvesters have focused on single energy sources including mechanical (force [ 3,4 ] and friction [ 5 ] ), electromagnetic (light and magnets [ 6 ] ), or thermal energy, and huge advances have been made in improving their efficiencies. However, focusing on a single energy source means that much of the available energy for harvesting is ignored.…”

“…Thus, to provide higher energy and power output, small-scale energy harvesters must be found that increase utilization of the total available environmental energy. Traditional energy harvesters have focused on single energy sources including mechanical (force [3,4] and friction [5] ), electromagnetic (light and magnets [6] ), or thermal energy, and huge advances have been made in improving their efficiencies.…”

Energy Interplay in Materials: Unlocking Next‐Generation Synchronous Multisource Energy Conversion with Layered 2D Crystals

et al. 2022

Layered 2D crystals have unique properties and rich chemical and electronic diversity, with over 6000 2D crystals known and, in principle, millions of different stacked hybrid 2D crystals accessible. This diversity provides unique combinations of properties that can profoundly affect the future of energy conversion and harvesting devices. Notably, this includes catalysts, photovoltaics, superconductors, solar‐fuel generators, and piezoelectric devices that will receive broad commercial uptake in the near future. However, the unique properties of layered 2D crystals are not limited to individual applications and they can achieve exceptional performance in multiple energy conversion applications synchronously. This synchronous multisource energy conversion (SMEC) has yet to be fully realized but offers a real game‐changer in how devices will be produced and utilized in the future. This perspective highlights the energy interplay in materials and its impact on energy conversion, how SMEC devices can be realized, particularly through layered 2D crystals, and provides a vision of the future of effective environmental energy harvesting devices with layered 2D crystals.
