The photocatalytic production of hydrogen (H) from water is a vital avenue towards sustainable energy and addressing global environmental challenges. To maximize efficiency, harnessing the synergistic effects of multiple co-catalysts is essential, as these interactions can significantly enhance performance. In this study, we introduce a ternary heterojunction composed of a nickel-imidazole framework (Ni-MOF), graphitic carbon nitride (CN), and TiC MXene (TC), employing solvothermal and wet impregnation methods, featuring a well-designed Type II heterojunction and a noble metal-free Schottky junction for efficient hydrogen evolution.

Article Synopsis
  • Silicon carbide (SiC) diodes are being explored for radiation detection applications due to their excellent properties, with studies indicating that replacing metal contacts with an epitaxially-grown graphene layer (EG) can enhance performance.
  • The research at IMB-CNM demonstrated that SiC detectors both with and without graphene were tested for charge collection, using methods like radioactive source interaction and transient current technique (TCT).
  • Results showed that the EG-SiC sensors achieved effective charge collection and uniform response, with up to 40% less transient amplitude damping compared to devices without metallic contacts, indicating the potential of graphene in improving radiation detection performance.

Metal-Organic Frameworks (MOFs) are extensively used as electrode material in various sensing applications due to their efficacious porous nature and tunable properties. However, pristine MOFs lack conductive attributes that hinder their wide usage in electrochemical applications. Electropolymerization of several aromatic monomers has been a widely used strategy for preparing conducting electrode materials for various sensing applications in the past decades.
