Oxygen reduction reaction (ORR) has attracted considerable attention for clean energy conversion technologies to reduce traditional fossil fuel consumption and greenhouse gas emissions. Although platinum (Pt) metal is currently used as an electrocatalyst to accelerate sluggish ORR kinetics, the scarce resource and high cost still restrict its further scale-up applications. In this regard, biomass-derived carbon electrocatalysts have been widely adopted for ORR electrocatalysis in recent years owing to their tunable physical/chemical properties and cost-effective precursors. In this minireview, recent advances of the optimization strategies in biomass-derived carbon electrocatalysts towards ORR have been summarized, mainly focusing on the optimization of pore structure and active site. Besides, some current challenges and future perspectives of biomass-derived carbon as high-performance electrocatalysts for ORR have been also discussed in detail. Hopefully, this minireview will afford a guideline for better design of biomass-derived carbon electrocatalysts for ORR-related applications.

Recently, molybdenum diselenide (MoSe2) has attracted nascent research attention for potential applications in electronic and optoelectronic devices due to its unique properties including tunable bandgap, strong photoluminescence and large exciton binding energy. However, the synthesis of reproducible, controlled and large scale MoSe2 films is still a great challenge. Here, we have investigated the morphology, structure and crystalline quality of MoSe2 films synthesized by the selenization of Mo metal films. The Mo metal films of different thicknesses were deposited at room temperature by direct current sputtering. Subsequently, MoSe2 films were prepared by selenization of sputtered Mo films at 550 °C for 20 minutes. The obtained MoSe2 films are polycrystalline with hexagonal crystal structure. The crystalline quality of the MoSe2 films is improved with increase in the thickness of Mo metal films. The MoSe2 films are found to be n-type in nature and reasonably stoichiometric (Mo/Se ratio ∼1:1.9). This study provides an experimental demonstration of an alternative cost-effective direct synthesis of MoSe2 films on SiO2/Si for the applications of semiconductor devices.
