Abstract

Hydrogen energy storage has been considered as a key enabler for exploring novel materials with unique structures and properties, however, inadequate storage capacity, and instability leading to low performances. Metal organic compounds contain a core transition metal ion in accordance to their organic environment, allowing localized and enhanced hydrogen storage. Here, we show a superior hydrogen storage system, with around 1850 mAh/g discharge capacity and around 74% charge-discharge efficiency, performing rectangular nanocuboids beta copper phthalocyanine (β-CuPc). Primarily, β-CuPc has been synthesized in ethylene glycol (EG) via stepwise thermal treatments up to ∼185 °C with demonstrating its morphological and structural properties. Interestingly, unique surface morphology of as-synthesized β-CuPc (with about 163 nm width and 47 nm height) comes to our preliminary expectations as a relevant host for hydrogen sorption. Our work can expand into the classes of materials that can be used efficiently in hydrogen storage technology, and also opening a new channel to the wide range of mobile applications, either in academia or industries.
