Summary: Fabricating low-cost, earth-enriched and high-performance electrocatalysts for hydrogen evolution reaction (HER) is significant but challenging. In this study, superhydrophilic molybdenum phosphide quantum dots on porous carbon matrix (MoP-QDs@PC) were prepared using polyoxometalates (POMs)-contained metal organic frameworks (MOFs) as precursors. The as-prepared MoP-QDs@PC electrocatalyst exhibits excellent HER performance, outperforming commercial 20% Pt/C electrocatalyst under alkaline and acidic conditions. This research provides a feasible and reliable strategy for developing economical, efficient and stable electrocatalysts for hydrogen evolution.

Summary: Crystalline porous materials have been extensively explored for various applications in nonlinear optics, due to their structural diversity and flexibility in organizing dipolar chromophores. Recent advances in the field have focused on second-order NLO in chiral and achiral structures, as well as third-order NLO in pure organic and hybrid organic/inorganic materials. The future challenges and research directions of these materials have also been proposed.

Summary: In this study, CuH{PMo12O40}@Cu(Melamine) ({PMo12O40}@Cu-Melamine) and nitrogen-doped carbon-coated copper and molybdenum carbide (Cu-Mo2C@NC) were synthesized and their supercapacitor performance was compared. It was found that Cu-Mo2C@NC exhibited higher specific capacitance, better cycle stability, and higher energy density compared to {PMo12O40}@Cu-Melamine.

Summary: In this study, high-density Lewis acid sites were created and engineered on the surfaces of porous single-crystalline Mo2N and MoN monoliths to enhance the non-oxidative dehydrogenation of propane to propylene. The top-layer Mo ions with specific coordination structures provided effective activation of C-H bonds without overcracking of C-C bonds, resulting in propane conversion of approximately 11% and propylene selectivity of approximately 95% at 500 degrees C.

Summary: We develop a method of pre-melting and resolidification of chalcogen precursors for chemical vapor deposition growth of 2D transition metal dichalcogenides (TMDCs), resulting in TMDCs with ultrahigh quality and uniformity. Taking WS2 as an example, the monolayer WS2 shows uniform fluorescence intensity and narrow photoluminescence peak, indicating high structural quality and uniformity. This method is also applicable to the growth of other TMDCs like MoS2, WSe2, MoSe2.

Summary: This study designs a porous carbon-based sulfur electrode for high-energy Li-S batteries. By impregnating the porous carbon with a high concentration of sulfur and reducing the content of conductive agent and binder, crack formation during electrode drying can be inhibited. Two distinct electrically conducting networks are utilized to reduce battery polarization and achieve a capacity of 690 mAh g(-1) even after 100 cycles. Pouch cells are prepared to evaluate the practical performance, resulting in a capacity of 741 mAh and a cathode energy density of 1001 Wh kg(-1). These findings are expected to guide the further development of high-energy-density cathode materials for Li-S batteries.

Summary: Improved methods for the synthesis of linear and cyclic poly(diphenylacetylene)s using MoCl5- and WCl4-based catalytic systems have been developed. MoCl5 induces migratory insertion polymerization of diphenylacetylenes in the presence of arylation reagents such as Ph4Sn and (ArSnBu3)-Bu-n to produce cis-stereoregular linear poly(diphenylacetyelene)s with high molecular weights. On the other hand, WCl4 induces ring expansion polymerization of diphenylacetylenes in the presence of Ph4Sn or reducing reagents to produce cis-stereoregular cyclic poly(diphenylacetylene)s with high molecular weights. Both catalytic systems are applicable to the polymerization of various diphenylacetylenes having polar functional groups such as esters that are not efficiently polymerized by conventional methods.

Summary: Layered semiconducting transition metal dichalcogenides (TMDs) have excellent optoelectronic properties, but practical contacts to TMDs have poor charge carrier selectivity, leading to low open-circuit voltage (V-OC) and limited power conversion efficiency (PCE). A simple MoOx (x approximate to 3) surface charge-transfer doping and passivation method was applied to multilayer tungsten disulfide (WS2) solar cells to address these issues, resulting in lateral p-n junction photovoltaic cells with a record V-OC of 681 mV, the highest among all p-n junction TMD solar cells with a practical design, and leading to record PCE in ultrathin (<90 nm) WS2 photovoltaics.
