In response to the ongoing energy crisis, advancing the field of electrocatalytic water splitting is of utmost significance, necessitating the urgent development of high-performance, cost-effective, and durable hydrogen evolution reaction catalysts. But the generated gas bubble adherence to the electrode surface and sluggish separation contribute to significant energy loss, primarily due to the insufficient exposure of active sites, thus substantially hindering electrochemical performance. Here, we successfully developed a superaerophobic catalytic electrode by loading phosphorus-doped nickel metal （NiPx） onto various conductive substrates via an electrodeposition method. The electrode exhibits a unique surface structure, characterized by prominent surface fissures, which not only exposes additional active sites but also endows the electrode with superaerophobic properties. The NiPx/Ti electrode demonstrates superior electrocatalytic activity for hydrogen evolution reaction, significantly outperforming a platinum plate, displaying an overpotential of mere 216 mV to achieve a current density of-500 mA cm-2in 1 M KOH. Furthermore,the NiPx/Ti electrode manifests outstanding durability and robustness during continuous electrolysis, maintaining stability at a current density of-10 mA cm-2over a duration of 2000 h. Owing to the straightforward and scalable preparation methods, this highly efficient and stable NiPx/Ti electrocatalyst offers a novel strategy for the development of industrial water electrolysis.

Gomphus purpuraceus is an ancient wild edible mushroom. However， the niche and lignocellulose degradation system of G. purpuraceus have remained cryptic. In the current study， transcriptome and proteome sequencing of G. purpuraceus in four mediums was performed. A total of 3489 differentially expressed genes (DEGs) and 891 differentially expressed proteins (DEPs) were screened out. For the lignocellulose degradation system， a total of 61 expressed genes were annotated， including 19 genes encoding cellulase， 8 genes encoding hemicellulase， 5 genes encoding pectinase， 22 genes encoding lignin oxidase， and 7 lignin degrading auxiliary enzyme. From two-omics， morphology， and enzyme activities， we speculated that G. purpuraceus might have a limited capacity to degrade polysaccharides (starch and lignocellulose). In addition， trace amount of fumonisins (FB1 and FB2) were found in the G. purpuraceus. These results provided a new perspective for understanding the key pathways and hub genes involved in carbon metabolism of G. purpuraceus development.
