Themed collection RSC Advances Energy Chemistry year in review 2024

Focus on the progress of electrode materials for supercapacitors using composite materials based on CPs, metal oxide NPs, and CNTs. Both electrolyte-based and electrolyte-free supercapacitors are also discussed in detail.

Production, storage and transportation are the three key areas of development for hydrogen as a sustainable energy source.

Ni_xP/C fiber mat interlayers with tailored surface oxidation layers exhibit strong polysulfide adsorption and catalytic conversion, enhancing lithium–sulfur cell stability by up to 200 cycles at 2C with a discharge capacity of ∼800 mA h g⁻¹.

The new architecture of MAPbI₃-based solar cells with photovoltaic parameters. The inset shows a new schematic design of the n-i-p structure for the PSC used in SCAPS simulation: AZO/SnO₂/MAPbI₃ with excess PbI₂/spiro-OMeTAD/IZO.

Pt/Cs synthesized via particle ALD demonstrate increased PEM fuel cell durability over 30 000 cycles of Pt dissolution testing, attributed to their narrow Pt size distribution and high Pt dispersity.

Storage performance of spray-pyrolyzed Mn₃O₄ electrode varied significantly with electrolytes and maximum specific capacitance was achieved in K₂SO₄. Phase transformation from Mn₃O₄ to MnO₂ was observed with cycling, regardless of the electrolyte.

Mesoporous TiO₂ thin films with a crystalline structure were effectively produced and analyzed after modification with Fe and Ni porphyrins. The collaborative impact of these metal complexes was evaluated to determine if the simultaneous presence of both metalloporphyrins enhances the OER activity.
