主　　题：low-oxygen condition oxygen reduction reaction(ORR) oxygen level control for microenvironment electrochemical oxygen removal 

摘      要：Low-oxygen(O_(2))environments are essential in various research and application fields,yet traditional methods like nitrogen flushing or chemical O_(2) absorbers face challenges in high equipment cost and low *** study introduces a novel electrochemical oxygen removal(EOR)controller,offering a lightweight,low-cost,and precise low-O_(2) control *** self-powered EOR controller uses a sacrificial anode to drive the cathodic oxygen reduction reaction(ORR),efficiently consuming environmental O_(2) to reduce its level,thus eliminating the requirements of external gas or power *** integrating a single-atom ORR catalyst and flexible design,the device achieves a substantial reduction in weight and *** incorporation of electronic components for the EOR controller,including a switch for reaching targeted O_(2) concentration and a fixed resistor for O_(2) removal rate regulation,enables multi-dimensional O_(2) removal *** system also realizes the O_(2) concentration estimation in real-time with±1%accuracy(within the 21%-1% range)by calculating electron *** EOR controller s effectiveness is validated in plant hypoxia stress experiments,demonstrating precise O_(2) level adjustments and its potential across various applications requiring controlled hypoxic conditions.
