Summary: In this study, N-doped carbon nanosphere-stabilized Pd nanoparticles were synthesized as high-efficiency nano-catalysts for selective and controlled H-2 generation upon additive-free HCOOH dehydrogenation. The enrichment of electron cloud density of Pd atoms by graphitic N/C in NCS-800 was favorable for the cleavage of C-H bonds. Furthermore, the selective H-2 evolution from additive-free HCOOH dehydrogenation over Pd/NCS-800 was successfully controlled by adjusting the pH.

Summary: A facile novel B, N co-doped carbon was prepared by high-temperature pyrolysis of ethylenediamine tetraacetic acid disodium salt and boric acid mixture. Pd nanoparticles were loaded onto the carbon material to synthesize highly efficient Pd/BNC catalyst for formic acid dehydrogenation. The doping of B elements regulated the type and content of N, providing more anchor sites for Pd and enhancing the interaction between support and Pd nanoparticles, resulting in highly dispersed Pd nanoparticles and regulated electronic properties of Pd. The obtained Pd/BNC catalyst displayed enhanced performance and lower activation barrier, as well as excellent cycling stability for hydrogen evolution from formic acid.

Summary: Two Cu(II) (C1) and Ni(II) (C2) complexes were synthesized and characterized, showing distorted octahedral geometry. MTT assays revealed that the complexes have significant antiproliferative effects on BEL-7404 cells, with C1 being more potent than C2. Cellular uptake of the complexes suggests that different levels of ROS production may contribute to their differential cytotoxicity. Mechanistically, C1 induces apoptosis through a caspase-dependent mitochondrion pathway, while C2 induces BEL-7404 cell death through the RAGE/PI3KC3/Beclin 1 autophagic cell signaling pathway.

Summary: In this study, a Fe2O3/CNT/MIL heterostructure was developed for the degradation of ofloxacin (OFX) antibiotics under visible light irradiation (λ > 420 nm). The introduction of α-Fe2O3 and NH2-MIL-125 enhanced the separation of photogenerated electron-hole pairs, resulting in a high photodegradation rate of OFX. The loading of SWCNTs improved the electrical conductivity of α-Fe2O3 and NH2-MIL-125, further enhancing the photodegradation activity. (OH)· and O·2- were identified as the main active species responsible for the degradation process.

The catalyst consists of aluminum-oxygen chains as the metal center and transition metal sites, and has achieved satisfactory CO2-to-CO conversion with a Faradaic efficiency as high as 90% and long-term stability over 35 hours under visible light. The improved performance is attributed to the stability provided by the aluminum-oxygen chains, the efficient charge transfer rate facilitated by the transition metal sites, and the accelerated charge transfer by visible light.

Summary: p_Aminophenol, also known as 4-aminophenol (4-AP), is a chemical compound with hydroxyl and amino groups on the benzene ring. It is a suitable precursor for synthesizing oxazoles and oxazines. However, the toxicity of aniline and phenol poses a risk to human and environmental health, so it is important to develop reliable techniques for detecting and eliminating trace amounts of amino phenols.

Summary: Three nickel substituted Keggin-type polyoxometalates (SiW9Ni3) were selectively intercalated into Zn3Al based Layered Double Hydroxide (Zn3Al-LDH) using ion-exchange technique. The resulting nanocomposite, SiW9Ni3@Zn3Al, acted as a heterogeneous nanoreactor for the synthesis of drug-like aminoimidazopyridine small molecules via Ugi-type Groebke-Blackburn-Bienayme reaction (GBB 3-CRs) without any acid/additive under mild and solvent-free conditions. The catalytic property of SiW9Ni3@Zn3Al was enhanced compared to the individual components, indicating a synergistic catalytic effect between SiW9Ni3 polyoxometalate and Zn3Al-LDH precursors. The Lewis/Bronsted acidity of SiW9Ni3 polyoxometalate and Zn3Al-LDH precursors played essential roles in the catalytic performance of the composite.
