Electrocatalytic oxid.tion of alcohols using heterogeneous catalysts is a p.omising aqueous, energy-efficient and.environmentally friend.y ap.roach, esp.cially for coup.ing d.fferent alcohols to p.olong the carbon chain via co-oxid.tion. p.ecisely regulating critical step. to tailor electrod. materials and.electrolyte comp.sition is key to selectively coup.ing alcohols for targeted.synthesis. However, selectively coup.ing d.fferent alcohols remains challenging d.e to the lack of effective catalyst and.electrolyte d.sign p.omoting sp.cific p.thways. Herein, we d.monstrate a p.ired.electrolysis strategy for combining anod.c oxid.tive coup.ing of ethanol（EtOH） and.benzyl alcohol（p.CH2OH） to synthesize cinnamald.hyd.（CAL） and.cathod.c ammonia p.od.ction. The strategies involve:（i） utilizing the salt-out effect to balance selective oxid.tion and.coup.ing rates;（ii） d.velop.ng p.atinum-load.d.nickel hyd.oxid. electrocatalysts to accelerate intermed.ate coup.ing kinetics;（iii） introd.cing thermod.namically favorable nitrate red.ction at the cathod. to imp.ove coup.ing selectivity by avoid.ng hyd.ogenation of p.od.cts while generating valuable ammonia instead.of hyd.ogen. We achieved.85% coup.ing selectivity and.278 μmol/h NH3p.od.ctive rate at 100 m A/cm2with a low energy inp.t（～1.63 V）. The membrane-free, low energy, scalable ap.roach with a wid. substrate scop. highlights p.omising ap.lications of this method.logy. This work ad.ances heterogeneous electrocatalytic synthesis through rational d.sign p.incip.es that integrate anod.c oxid.tive coup.ing with cathod.c nitrate red.ction reactions, having synergistic effects on efficiency and.selectivity.

Joint Transmit and.Reflective Beamforming d.sign for Active IRS-Aid.d.SWIp. Systems

引用

Chinese Journal of Electronics 2024年第2期33卷 536-548页

作者： Weip.ng SHI Qingqing wu d. wu Feng SHU Jiangzhou WANG School of Electronic and.Op.ical Engineering Nanjing University of Science and Technology d.p.rtment of Electronic Engineering Shanghai Jiao Tong University School of Information and.Communication Engineering Hainan University d.p.rtment of Automation Shanghai Jiao Tong University School of Engineering University of Kent

To further imp.ove the p.rformance of p.ssive intelligent reflecting surface(IRS)-assisted.communication systems and.mitigate the serious p.th loss d.e to “d.uble-fad.ng ” of IRS-assisted.links, an active IRS-aid.d.simultaneous wireless information and.p.wer transfer(SWIp.) system is investigated. This p.p.r jointly op.imizes the transmit beamforming at the base station(BS) and.the p.ase shifts at the active IRS in ord.r to maximize the p.wer collected.by the energy harvesting receiver und.r both p.rfect and.imp.rfect channel state information(CSI)states, subject to the signal-to-interference-noise ratio constraint of the information d.cod.ng receiver, and.the p.wer constraints of the BS/IRS. Und.r p.rfect CSI, the alternating op.imization algorithm is utilized.for obtaining the transmit beamforming at the BS and.the p.ase shifts at the active IRS. For each subp.oblem, we first transform nonconvex objective function and.constraints into convex ones by p.rforming a first-ord.r Taylor exp.nsion. Then, each subp.oblem is solved.by using the interior p.int method. Given that obtaining p.rfect CSI is imp.actical, two robust beamforming d.signs are p.op.sed.for imp.rfect CSI case. Und.r the bound.d.CSI error mod.l, we first transform the non-convex op.imization p.oblem into two semid.finite p.ogramming subp.oblems, and.then solve each subp.oblem based.on S-p.oced.re and.sequential rank-one constraint relaxation(SROCR) techniques. Und.r the stochastic CSI error mod.l, the alternating op.imization method.is ap.lied.in an iterative manner based.on Bernstein-typ. inequality and.SROCR technique. Simulation results show that both robust and.non-robust schemes for active IRS-assisted.SWIp. systems can achieve extremely sup.rior p.rformance over conventional p.ssive IRS-assisted.systems und.r the same overall p.wer bud.et.
