Summary: The efficient conversion of CO2 to value-added products, particularly electrochemical CO2 reduction to formic acid, is a promising solution to mitigate climate change. P-block metals, specifically Bi, Sn, In, and Pb, have shown to be efficient catalysts for CO2 electroreduction to formate. However, industrial-scale implementation faces remaining challenges. This review comprehensively discusses the current research status, challenges, and prospects of p-block metal-based catalysts for CO2 electroreduction to formate, including rational design, nanostructure engineering, operando characterization techniques, and future directions.

Summary: The hydrogen evolution reaction (HER) is crucial for sustainable development and carbon neutrality. Researchers have found that the d-band frontier descriptor of Pt single atoms on transition metal disulfides (Pt1/TMDs) is highly correlated with the Gibbs energy of H* adsorption. This descriptor can also be applied to Pt single atoms anchored on other supports.

Summary: A straightforward synthesis of the first peraryl diboriranide was reported, demonstrating its preference for s-type coordination modes towards main group and transition metal centers. The synthesis involved the preparation of the non-classical diborirane from a readily available 1,2-dichlorodiborane(4) and subsequent conversion to the peraryl diboriranide lithium salt in three steps. Representative complexes with tin, copper, gold, and zinc were prepared and characterized to illustrate the reactivity and complexation behavior of the diboriranide.

Summary: The increased population and industrial revolution have resulted in higher atmospheric CO2 concentration, making it a global priority to find effective solutions to reduce CO2 emissions. The electrochemical CO2 reduction reaction (CO2RR) is believed to be a promising alternative for the production of value-added chemicals. However, the implementation of CO2RR is hindered by associated electrochemical reactions and the morphology of the catalyst plays a critical role in overcoming these drawbacks and enhancing product selectivity and efficiency.

Summary: In this study, density functional theory (DFT) simulations were used to investigate the site isolation strategy in electrocatalytic selective hydrogenation of acetylene. The results showed that isolated Cu metal sites have higher energy barriers on overhydrogenation and C-C coupling reactions. Based on this, Cu single-atom catalysts highly dispersed on nitrogen-doped carbon matrix were developed and demonstrated high ethylene selectivity under high concentrations of acetylene. The superior performance was attributed to the weak adsorption of ethylene intermediates and highly energy barriers on C-C coupling at isolated sites, as confirmed by both DFT calculations and experimental results. This study provides a comprehensive understanding of the isolated sites inhibiting the side reactions in electrocatalytic acetylene semihydrogenation.

Summary: This article proposes a novel amplitude-domain pulsewidth modulation (AD-PWM) technique for a three-phase energy-stored quasi-Z-source inverter (ES-qZSI) photovoltaic (PV) power system. The modulation technique performs switching states and shoot-through behavior based on the relationship of size among three-phase voltages, providing simplicity and low computation. The article further investigates the AD-PWM-based three-phase PV power system and integrates an active power control method with reactive power compensation, resulting in fast and reliable active power regulation. The proposed control strategy has advantages over existing schemes, including low computation and the ability to ensure grid-injected current tracking the grid voltage in phase.

Summary: This article proposes a single-phase five-level voltage inverter topology with six switches for renewable energy applications. The suggested inverter reduces switching and conduction losses with its low switch count and uses a multi-error feedback controller with modified sinusoidal pulse width modulation to maintain the output voltage within the desired range. The absence of clamping diodes and bulky capacitors enables the use of a simple model predictive controller, decreasing circuit cost and improving overall efficiency. Simulation and hardware results are provided to validate the originality of the study.

Summary: Properly disposing of waste polymers is a global challenge. Thermal degradation is a promising method for recycling polymer waste into energy-dense fuels or products without causing pollution. This study investigated the thermal degradation characteristics, kinetics, thermodynamic parameters, and volatiles of micron waste polypropylene (PP) pyrolysis in nitrogen. The results show that the thermal degradation of micron waste polypropylene is a one-step reaction with a peak and average reaction rates that decrease with heating rate. The most appropriate reaction model is determined and the kinetic parameters are larger than those of PP with larger particle sizes. The thermogravimetric curves match well with the experimental results, and the thermal degradation is found to be a non-spontaneous and endothermic reaction. The concentrations of volatiles are determined in descending order.
