Metal-organic frameworks for upgrading biogas via CO2 adsorption to biogas green energy.

Abstract: In the midst of the global climate change phenomenon, mainly caused by fossil fuel burning to provide energy for our daily life and discharge of CO2 into the atmosphere, biogas is one of the important renewable energy sources that can be upgraded and applied as a fuel source for energy in daily life. The advantages of the production of hybrid materials, metal–organic framework (MOF) adsorbents, expected for the biogas upgrading, rely on the bulk separation of CO2 under near-ambient conditions. This review highlights the challenges for MOF adsorbents, which have the greatest upgrading abilities for biogas via selective passage of methane. The key factors improving the ideal MOF materials for these high CO2 capture and selectivity uses for biogas upgrading to produce bio-methane and reduce fossil-fuel CO2 emission will be discussed.

A universal synthesis strategy for P-rich noble metal diphosphide-based electrocatalysts for the hydrogen evolution reaction

Abstract: Highly efficient, stable and cost-efficient electrocatalysts for hydrogen generation via water splitting have become in increasing demand for future energy systems. Hitherto, P-rich noble metal polyphosphides which can decrease noble metal (such as Rh, Pd, or Ir) dosage are important to probe potential high-performance HER electrocatalysts. Nevertheless, they are difficult to synthesize at ambient pressure and moderate temperatures. Herein, for the first time, we report a novel iridium diphosphide (IrP2) electrocatalyst embedded within an ultrathin nitrogen-doped carbon (NC) layer (IrP2@NC) synthesized at ambient pressure and moderate temperature (900 °C). Subsequent electrochemical tests revealed that such a P-rich IrP2@NC catalyst possesses the highest hydrogen evolution reaction (HER) activity among all the documented transition metal phosphide electrocatalysts, including the commercial Pt/C, with ultralow overpotentials of 8 and 28 mV to achieve 10 mA cm−2 in 0.5 M H2SO4 and 1.0 M KOH, respectively. Combined density functional theory (DFT) computational studies suggest that the introduction of phosphorus into iridium can weaken the H adsorption strength of IrP2, beneficial for boosting HER activity. More importantly, this synthetic strategy for P-rich IrP2@NC can also be applied to other noble metal diphosphides (RhP2@NC and Pd5P2@NC, etc.). This work presents a particularly efficient and stable P-rich transition metal polyphosphide with advanced HER performance and beyond.

Heteroatom-doped carbon dots: synthesis, characterization, properties, photoluminescence mechanism and biological applications.

Abstract: Heteroatom-doped carbon dots (CDs), due to their excellent photoluminescence (PL) properties, attracted widespread attention recently and demonstrated immense promise for diverse applications, particularly for biological applications. The objective of this feature article is to provide a comprehensive overview of the recent progress in the research and development of heteroatom-doped CDs and a detailed description of the influence of single or co-doping heteroatoms on their PL behavior. The most recent understanding and critical insights into the PL mechanism of heteroatom-doped CDs are also highlighted. Moreover, potential bio-related applications of heteroatom-doped CDs in biosensing, bioimaging, and theranostics are also reviewed. This state-of-the-art review will provide a platform for understanding the intricate details of heteroatom-doped CDs, a summary of the latest progress in the field, and related applications in biology and is expected to inspire further developments in this exciting class of materials.
