TL;DR: This study suggests that using beta-MnO(2) instead of Pt could potentially improve the feasibility of scaling up MFC designs for real applications by lowering production cost.

Abstract: A new inorganic solid state electrocatalyst for the hydrogen evolution reaction (HER) is reported. Highly crystalline layered ternary sulfide copper-molybdenum-sulfide (Cu2MoS4) was prepared by a simple precipitation method from CuI and [MoS4]2− precursors. In aqueous solution and over a wide pH range (pH 0 to 7), this Cu2MoS4 showed very good catalytic activity for HER with an overvoltage requirement of only ca. 135 mV and an apparent exchange current density of 0.040 mA cm−2 (Tafel slope of ca. 95 mV per decade was found irrespective of the pH value). This Cu2MoS4 catalyst was found to be stable during electrocatalytic hydrogen generation. Therefore, it represents an attractive alternative to platinum.

TL;DR: In this article, the influence of platinum size on the electrocatalytic reduction of oxygen molecules in both hot phosphoric acid and sulphuric acid has been examined, and it is shown that when the intercrystallite distance is greater than an average of 20 nm, the apparent specific activity is fully achieved for all electrocatalyst dispersions.
