Synthesis and Materials Design of New Transient Metal Peroxide and Superoxide based on Physical Transport Process in liquid Ammonia

I had proposed new methods for synthesizing novel molecular crystals: transient metal (TM) peroxide/superoxide, which had never found in the crust of Earth. I am interested in novel electric functions based on spin-orbital interactions of 4d or 5d TM and first I tried to synthesize both bulk and thin films by the reaction between (1) reduced oxygen molecules (O-O-) and 4d/5d TM and (2) oxygen plasma (O-O+) and 4d/5d TM, however, no novel materials were obtained. I discussed in parallel on the introduction of peroxide anions over the TM surface by the deep-UV light irradiation and this process would partially succeeded. A TM oxide heterojunction device were manufactured and its novel functions, photo-induced charge transfer between aromatic VOC (Volatile Organic Compound) adsorbate and peroxide anions. Novel gas sensing properties were found out in the system NiO-ZnO, which will be applicable for high-performance VOC sensors.
