Liquid metal(LM)has attracted immense interest as a novel catalyst in the past few years for its distinctive physicochemical properties,encompassing superior electrical and thermal conductivities,as well as exceptional fluidity characteristics at low temperatures[1].In contrast to conventional solid heterogeneous catalysts,the fluidic characteristics of liquid metal catalysts enhance the interaction between catalysts and reactants,boosting mass transfer at the reaction interface.

The North Pacific storm track (NPST) is a high-frequency area of extratropical cyclones and an important channel for water vapor and energy transfer between low and mid-high latitudes. Previous weather and dynamic studies in this region have made significant progress, but due to the lack of ocean surface rainfall observation data, there is a lack of statistical research on precipitation in this area. In this study, statistical research on the spatiotemporal distribution characteristics of NPST rainfall was conducted based on GPM DPR (Global Precipitation Measurement Dual-frequency Precipitation Radar) observation data and ERA5 atmospheric parameters, and analysis and explanations are provided based on the atmospheric *** study found that, compared to low-pressure systems, pressure gradients have a greater impact on cyclone activity and rainfall distribution. This feature, along with the meridional distribution of high atmospheric water vapor in the North Pacific Ocean and low in the north, collectively leads to the offset of high-frequency rainfall areas relative to storm tracks. The distribution of sea surface temperatures in the North Pacific Ocean affects the zonal distribution of storm tracks, causing weather disturbances and precipitation along the storm tracks to exhibit a northward extension from west to east. This study deepens our understanding of the role of NPST in global-scale water vapor and energy balance, and is of great significance for improving the prediction accuracy of climate models with respect to rainfall generated by extratropical cyclones.

Dissolved copper and iron ions are regarded as friendly and economic catalysts for peroxymonosulfate(PMS)activation,however,neither Cu(Ⅱ)nor Fe(Ⅲ)shows efficient catalytic performance because of the slow rates of Cu(Ⅱ)/Cu(Ⅰ)and Fe(Ⅲ)/Fe(Ⅱ)***,we observed a significant enhancement on the degradation of organic contaminants when Cu(Ⅱ)and Fe(Ⅲ)were coupled to activate PMS in borate(BA)*** degradation efficiency of Rhodamine B(RhB,20μmol/L)reached up to 96.3%within 10 min,which was higher than the sum of individual Cu(Ⅱ)-and Fe(Ⅲ)-activated PMS *** radical,hydroxyl radical and high-valent metal ions(i.e.,Cu(Ⅲ)and Fe(IV))were identified as the working reactive species for RhB removal in Cu(Ⅱ)/Fe(Ⅲ)/PMS/BA system,while the last played a predominated *** presence of BA dramatically facilitated the reduction of Cu(Ⅱ)to Cu(Ⅰ)via chelating with Cu(Ⅱ)followed by Fe(Ⅲ)reduction by Cu(Ⅰ),resulting in enhanced PMS activation by Cu(Ⅰ)and Fe(Ⅱ)as well as accelerated generation of reactive ***,the strong buffering capacity of BA to stabilize the solution pH was satisfying for the pollutants degradation since a slightly alkaline environment favored the PMS activation by coupling Cu(Ⅱ)and Fe(Ⅲ).In a word,this work provides a brand-new insight into the outstanding PMS activation by homogeneous bimetals and an expanded application of iron-based advanced oxidation processes in alkaline conditions.
