A mixed flow of two immiscible liquids may form drops of one liquid in the other. Deformation and breakup of drops occur when there is sufficient hydrodynamic or surface forces from the ambient liquid; such deformation and breakup of drops is a common phenomenon in various engineering applications, such as oil-water flow in the petroleum recovery industry [1, 2., stirred dispersions in the chemical industry [3,4], and melted metal and cooling liquid interactions in the nuclear industry [5, 6]. A typical simplified model for the mechanism study is the behaviours of a single drop against its surrounding liquid.

High-performance electrocatalysts for water splitting at all pH values have attracted considerable interest in the field of sustainable hydrogen evolution. Herein, we report an efficient electrocatalyst with a nanocrystalline cobalt phosphide （COP） network for water splitting in the pH range of 0-14. The novel flexible electrocatalyst is derived from a desirable nanocrystalline CoP network grown on a conductive Hastelloy belt. This kind of self-supported CoP network is directly used as an electrocatalytic cathode for hydrogen evolution. The nanocrystalline network structure results in superior performance with a low onset overpotential of N45 mV over a broad pH range of 0 to 14 and affords a catalytic current density of 100 mA-cm 2.even in neutral media. The CoP network exhibits excellent catalytic properties not only at extreme pH values （0 and 14） but also in neutral media （pH = 7）, which is comparable to the behavior of state-of-the-art platinum-based metals. The system exhibits an excellent flexible property and maintains remarkable catalytic stability during continuous 100-h-long electrolysis even after 100 cycles of bending/extending from 100° to 2.0°.
