Professor Ho, a member of the National Academy of Engineering, is a global leader in molecularly-based separations including definition of approaches, design of practical systems, scale-up and commercialization, and in the development of innovative membranes for molecular and chemical separations, including CO2 separation and capture, hydrogen purification, water desalination and purification, antibiotic recovery, and wastewater metal recovery. 

His specific accomplishments include:

  • The first to propose, synthesize, and experimentally demonstrate novel CO2-selective membranes capable of possessing high CO2 permeability and CO2/H2 selectivity (>80) at relatively high temperatures (100 – 180oC) for H2 purification and CO2 capture.  The membranes have been synthesized by incorporating amino groups in polymer networks.  Also the first to elucidate the unusual phenomenon of both permeability and selectivity increases with temperature.  He and his students removed H2S to <10 ppb in syntheses gas.  They were also the first to obtain <10 ppm CO in the H2 product with a water-gas-shift (WGS) membrane reactor using the membrane to drive the WGS reaction to the product side via CO2 removal.  The data were in good agreement with their model prediction.  This was the first CO2-selective membrane WGS reactor.  The membrane is being scaled up for commercialization, including its use in H2 purification for fuel cells.
  • Developed the novel concept of incorporating hydrophilic groups chemically into membrane structure to provide an additional pathway for water transport and to overcome the low hydrophilicity/flux issue inherent in interfacially polymerized membranes.  This work has resulted in >100% increase in water flux vs. the industry standard Film-Tec FT-30 membrane while maintaining a high NaCl rejection of >99%.  Working with an industrial partner, he has recently scaled up this membrane successfully to the commercial size of 42 inches in width and a length of about 2000 ft.  The membrane modules fabricated from this scale-up membrane are being tested by the U. S. Bureau of Reclamation at the Brackish Groundwater National Desalination Research Facility in Alamogordo, NM.  The initial results have confirmed the superior performance. 
  • Developed novel proton-exchange membranes (PEMs) synthesized from copolymers containing sulfonated hard segments for proton conductivity and hydrophilic soft segments for water retention.  The PEMs have shown very high conductivity (0.1 S/cm at 0 – 50% relative humidity, exceeding DOE’s target), which is much higher than Nafion® at 120oC, and they have also exhibited effective conductivity at 25oC.  The novel membranes have also exhibited high fuel cell performance and can enable the widespread use of PEM fuel cells.
  • Developed novel supported liquid membranes with strip dispersion for removal and recovery of indium from aqueous solutions and antibiotic (Cephalexin) from enzymatic synthesis mixtures.  This work has resulted in effective recovery of indium for reuse in a commercial plant and effective Cephalexin recovery from enzymatic mixtures without enzyme deactivation, which commonly occurs when complexation is conducted in enzymatic reaction mixtures.
  • Developed biocompatible and biodegradable poly(caprolactone) membranes with ~55 nm pores capable of a constant drug release rate for implantable drug delivery devices.  This work has resulted in disappearance of cancer tumors in mice.
