Triazine-containing covalent organic polymers (TCOPs) with unique structures and physicochemical properties are of great potential in energy storage and conversion applications, yet how to finely tune the morphology, and the accessible active sites, and to enhance capacitive activity remains a challenge. Here, the grid-like multilocular spheres derived from TCOP with abundant redox active sites and unique structures are fabricated via a molecular twist-induced regulation strategy, of which the number and size of cavities can be finely modulated by changing the conformers of the twisted unit and the Ostwald ripening time. The unique structure of the as-fabricated TCOP results in unprecedented high specific capacitance (8412 F g at 1 A g) and enables the as-assembled supercapacitor with an ultra-high energy density of 675 Wh kg in redox-active electrolyte (KI-mixed HSO), much better than all reported aqueous supercapacitors thus far.

The quest for stable and high-performance photocatalysts is pivotal in advancing the field of photocatalytic CO reduction. Traditional single-component semiconductors are often impeded by their inability to concurrently achieve a broad light absorption spectrum, efficient separation of photogenerated charge carriers, and enduring stability, thereby constraining their photocatalytic efficacy. In this study, we introduce an innovative hm-CN/CdS heterojunction that broadens the light absorption spectrum and significantly enhances the separation efficiency of photogenerated charge carriers.

Pd-based alloys are among the most attractive catalysts for direct alcohol fuel cells. However, their widespread use is limited by the high cost of Pd and their susceptibility to deactivation by surface-adsorbed reaction intermediates, particularly CO. In this study, we engineered an ultrathin 2D PdCr metallene to minimize Pd usage and doped it with phosphorus to enhance its CO tolerance.

Most self-powered electrochemical sensors (SPESs) are limited by low open circuit voltage and power density, leading to a narrow detection range and low sensitivity. Herein, a photoinduced Zn-air battery-assisted SPES (ZAB-SPES) is proposed based on cobalt and sulfur co-doped carbon nitride with the cyano group (Co, S-CN). The cyano functionalization remarkably enhances visible light utilization, and the cyano moiety acts as an electron-withdrawing group to promote electron enrichment.

The exploration of efficient, robust, and low-cost bifunctional electrocatalysts to drive the commercial application of Zn-air batteries (ZABs) is of great significance but still remains a challenge. Herein, a 1D coordination polymer (1D-CP) derived FeNi alloy & Co nanoparticles (NPs) co-implanted N-doped carbon nanosheets (FNC/NCS) is judiciously crafted and employed as a high-performance electrocatalyst for ultralong lifetime ZABs. The key to this strategy is the leveraging of metal-coordinated melamine to direct the pyrolysis of 1D-CP, enabling the in situ formation of well-dispersed FeNi alloy and Co NPs within the carbon matrix.

As a common biomass resource, wheat straw is gradually being derived as carbon materials for oxygen reduction reaction (ORR) in zinc-air batteries (ZABs). Herein, the wheat straw-derived carbon was prepared by ball milling and pyrolysis using deep eutectic solvent (DES) as the medium, which avoided the cumbersome procedures. The hydrogen bond of DES was utilized to reconstructed into a hydrogen bond network structure between DES and lignin/cellulose/hemicellulose of wheat straw.

Dove prisms suffer from angle and shift errors due to inevitable errors in manufacturing and installation, limiting their applicability in tasks requiring high-precision scanning. These errors, particularly angle errors, can significantly deform and ruin the intended scanning trajectory. Here, we propose a method for compensating the angle errors in Dove prisms using galvanometers.

Organic acid-based deep eutectic solvents (DESs) as catalysts always suffer from weak stability and low recyclability due to the accumulation of organic oxidative products in the DES phase. Herein, a completely inorganic deep eutectic solvent (IDES) ZnCl/PA with zinc chloride (ZnCl) and phosphoric acid (PA) as precursors is constructed to realize liquid-liquid interface catalysis for desulfurization of fuel and product self-separation for the first time. Owing to the inorganic nature, the organic oxidative products are accumulated at the interface between the IDES and fuel rather than the IDES phase.
