Summary: The construction of an ultrathin 2D ZnIn2S4/g-C3N4 Z-scheme heterojunction through in-situ growth of ZnIn2S4 on g-C3N4 allows for greatly improved hydrogen evolution performance by carefully regulating the interface structure. The optimized photocatalyst demonstrates significant photocatalytic activity without Pt, attributing to the synergistic effect of abundant active sites, enhanced photoresponse, and valid interfacial charge transfer channels. Spectroscopic analyses and density functional theory (DFT) calculations confirm that the enhanced photocatalytic performance is also due to promoted interfacial charge separation in the 2D Z-scheme heterojunction.

Summary: The Z-scheme heterojunction is promising in photocatalysis due to its efficient carrier separation and strong photoredox properties. However, regulating charge separation at the nanometric interface remains a challenge. In this study, we used g-C3N4 and MoS2 as models and designed the Mo-N chemical bond to connect the CB of MoS2 and VB of g-C3N4. The Mo-N bond acts as an atomic-level interfacial bridge, facilitating charge carrier migration between g-C3N4 and MoS2. Experiments confirmed that the Mo-N bond and internal electric field greatly enhance photogenerated carrier separation. The optimized photocatalyst exhibits a hydrogen evolution rate 19.6 times higher than pristine bulk C3N4. This study demonstrates the importance of atomic-level interfacial chemical bond design in heterojunctions and provides a new approach for efficient catalytic heterojunction design.

Summary: Modulating the electronic asymmetricity of catalysts is a new approach to improve electrocatalytic performance, but controlling the degree of asymmetry in heterostructured catalysts at the atomic level is still challenging. In this study, Ru nanoclusters were anchored on carbon materials doped with controllable N functional groups to optimize the electronic asymmetricity for efficient hydrogen evolution reaction (HER). By tailoring the type of N dopants, particularly pyrrolic-N, the electronic interaction between Ru and N species was manipulated, resulting in Ru-based heterostructures with excellent HER activity in basic media. Spectroscopy experiments and simulations confirmed that the asymmetric distribution of surface electrons in Ru-based heterostructures enhanced H2O adsorption and dissociation at positively charged interfacial Ru sites, and promoted hydrogen adsorption at negatively charged surface Ru sites, optimizing the elementary steps in the basic HER process. These findings provide crucial insights for the design and fabrication of advanced catalysts.

Summary: A Mo-doping BiVO4/ultrathin-CoAl-LDH (Mo:BVO/CoAl-LDH-u) photoanode with self-healing property is designed by using atomic layer CoAl-LDH as cocatalyst to modify Mo:BVO through dipping coating. The Mo:BVO/CoAl-LDH-u photoanode exhibits excellent surface charge separation efficiency and photocurrent density of 5.8 mA/cm2 without scavengers. CoAl-LDH-u enhances surface charge transfer efficiency and promotes the oxygen evolution reaction rate in Mo:BiVO4, while the self-healing property of Mo:BVO/CoAl-LDH-u allows for natural restoration of photoelectrochemical performance. This work provides a facile approach for fabricating high-efficiency BiVO4 photoelectrodes for PEC water splitting.

Summary: This study used portable emissions measurement systems (PEMS) to assess the on-road gaseous and particulate emissions from a gasoline direct injection (GDI) hybrid electric vehicle (HEV). Testing was conducted on three different driving routes representing urban, highway, and mountain driving conditions. Results showed that gaseous emissions were highest during mountain driving, while PM and soot emissions were comparable between urban and rural driving conditions but higher than highway driving. NOx emissions and soot emissions showed good correlation with vehicle acceleration but poor correlation with road grade.

Summary: MXenes are commonly considered to be catalytically inert, but a strategy of interfacial polarization is proposed to improve their catalytic activity. By constructing an interfacial structure consisting of black phosphorus (BP) nanoflakes and Nb2C MXene nanosheets, the catalytic performance of MXenes is enhanced for electrochemical nitrate reduction to ammonia. The strong interfacial polarization between BP nanoflakes and Nb2C nanosheets in the prepared BP/Nb2C composite leads to the formation of positively centered Nb atoms and BP-polarized Nb atoms, which synergistically catalyze the cleavage of N-O bonds in HNO2* to form NO*. The stabilization of monatomic *N by the BP/Nb2C composite is also improved. The ammonia yield rate and Faraday efficiency of the BP/Nb2C composite are significantly higher compared to BP nanoflakes and Nb2C nanosheets.

Summary: Photocatalytic water splitting using a semiconductor is an effective way to obtain clean energy. However, pure semiconductors have poor photocatalytic performance due to charge carrier recombination, limited light harvesting ability and deficiency of surface reactive sites. In this study, a new UiO-66-NH2/CdIn2S4 (NU66/CIS) heterojunction nanocomposite was synthesized using the hydrothermal method, which showed improved performance in water reduction. The NU66/CIS heterojunction had intimate connections and promoted effective transfer of electrons, resulting in enhanced H-2 production. This research offers a creative idea for constructing active MOF-based photocatalysts for H-2 evolution.

It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
