Keeping global warming at 2 degrees and below as stated in the "Paris Climate Agreement" and minimizing emissions can only be achieved by establishing a hydrogen (H) ecosystem. Therefore, H technologies stand out in terms of accomplishing zero net emissions. Although H is the most abundant element in the known universe, molecular H is very rare in nature and must be produced.

Recent advances in nanoparticle materials can facilitate the electro-reduction of carbon dioxide (CO) to form valuable products with high selectivity. Copper (Cu)-based electrodes are promising candidates to drive efficient and selective CO reduction. However, the application of Cu-based chalcopyrite semiconductors in the electrocatalytic reduction of CO is still limited.

Highly stable platinum (Pt) and ruthenium (Ru)-based catalysts on titanium oxide (TiO) nanoparticle support were prepared. The productivity of hydrogen generation from sodium borohydride (NaBH) hydrolysis was observed to be as high as 95%. The activation energies for the hydrolysis reaction in the presence of Ru/TiO in aqueous and alkaline solutions were 62.

In this study, three different morphologies, nanoflower (NF), nano sponge (NS), and nano urchin (NU), of zinc oxide (ZnO) nanostructures were synthesized successfully via a mild hydrothermal method. After synthesis, the samples were annealed in the atmosphere at 300, 600, and 800 °C. Although annealing provides different degradation kinetics for different morphologies, ZnO NS performed significantly better than other morphologies for all annealing temperatures we used in the study.

Mesoporous lithium metal phosphates are an important class of materials for the development of lithium ion batteries. However, there is a limited success in producing mesoporous lithium metal phosphates in the literature. Here, a lyotropic liquid crystalline (LLC) templating method was employed to synthesize the first examples of LiMPO (LMP) of Mn(II), Co(II), and Ni(II).
