Major Contributions
 

1.Developed a novel ionic rectifier (MXene@MC) featuring a steep channel gradient from angstrom-scale to mesoscale by capping an ultrathin 2D Ti₃C₂Tₓ MXene layer onto a single conical mesochannel, enabling strong ionic current rectification even at high electrolyte concentrations.

2.Demonstrated that the MXene@MC device achieves unprecedented osmotic conductance and power output, with a single channel reaching an osmotic conductance of 0.596 μS and a record osmotic power of 343 pW under a 1000-fold salinity gradient at neutral pH, outperforming all previously reported single-channel devices.

3.Provided both experimental and simulation evidence to elucidate the underlying physics of ion transport in asymmetrically structured ion-selective channels, establishing a new platform for advancing high-performance osmotic energy generators.

主要貢獻
 

1.創建一種新型離子整流器（MXene@MC），透過將超薄二維Ti₃C₂Tₓ MXene層覆蓋於單一錐形中孔尺度通道，實現從埃米級到中孔尺度的陡峭通道梯度，即使在高濃度電解質下亦能展現強大的離子電流整流能力。

2.證明MXene@MC裝置可達到前所未有的滲透導電度與功率輸出，單通道在1000倍鹽度梯度及中性pH條件下，滲透導電度高達0.596 μS，滲透功率創下343 pW紀錄，超越所有已報導之單通道裝置。

3.結合實驗與模擬，闡明非對稱結構離子選擇性通道中的離子傳輸物理機制，建立推動高效滲透能量發電器發展的新平台。
