1. 1. Electrocatalysts for sustainable hydrogen energy : disordered and heterogeneous nanomaterials

   Författare :Joakim Ekspong; Thomas Wågberg; Ludvig Edman; Tomas Edvinsson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Water splitting; Electrochemistry; Nanomaterials; Density functional theory; Hydrogen evolution; MoS2; Fuel cell; nanomaterials; nanomaterial; fysik; Physics; Physical Chemistry; fysikalisk kemi;

   Sammanfattning : With the current global greenhouse gas emissions, our remaining carbon budget is depleted in only 7 years. After that, several biophysical systems are predicted to collapse such as the arctic ice, coral reefs and the permafrost, leading to potentially irreversible consequences. LÄS MER

   Sammanfattning : This work focuses on the design, synthesis, characterization, and application projections of low-coordinated heavy pnictogen-containing (described by the generic letter E, hence E=C) phosphaalkenes (P=C) and arsaalkenes (As=C), with emphasis on the E=C group motifs. The work aims to understand their functional and modular character, reactivity, and potential applications by stabilizing, isolating, and characterizing these species in low-coordination environments.
