Webb3 nov. 2016 · Here, we report an effective method for achieving a broad range of shape evolution in CVD-grown monolayer MoS 2 flakes. By controlling the S and MoO 3 temperatures, the shape of the monolayer MoS 2 flakes was varied from hexagonal to triangular via intermediate shapes such as truncated and multi-apex triangles. Webb30 mars 2024 · The development of low-cost and efficient electrocatalysts for the oxygen evolution reaction (OER) is critical for enhancing the efficiency of the water-splitting reaction. Although MoS2 is a promising hydrogen evolution electrocatalyst, its oxygen evolution activity is significantly poor due to its weak ads
